Replaces duplicated CLAUDE.md content with one-line pointers into the sibling workspace repo, where the canonical text now lives: - Javadoc Conventions, SpotBugs Suppressions, jqwik prompt-injection policy: pointer per section - @VisibleForTesting design-fit / Package hierarchy / Class & method naming review TODOs: collapsed into a single workspace pointer - "Abstract guidelines to workspace" and "Standardised CLAUDE.md template" TODOs: marked DONE This repo had no per-repo SKILL.md (no .claude/skills/) and no in-repo writing guides, so only CLAUDE.md changes. https://claude.ai/code/session_01LzoKmqzgtQsELS5tsH4Wog
Workspace guides were restructured into a src/+test/ split with version-suffix file names. java-llama.cpp is Java 8, so only the -8.md baseline files apply. https://claude.ai/code/session_01LzoKmqzgtQsELS5tsH4Wog
Patch + minor version bumps verified safe against Maven Central: - checker-framework 4.1.0 -> 4.2.0 (minor) - logback-classic 1.5.33 -> 1.5.34 (patch) - fb-contrib 7.6.4 -> 7.7.4 (minor) - palantir-java-format 2.66.0 -> 2.91.0 (minor) - pitest-maven 1.25.1 -> 1.25.3 (patch) No source changes required. https://claude.ai/code/session_01LzoKmqzgtQsELS5tsH4Wog
Adds argsPackageIsALeaf to LlamaArchitectureTest: classes in net.ladenthin.llama.args must not depend on the root API package or the json parser package. Catches a future drift like an enum gaining a "convenient" helper that pulls in JNI state or a JSON DTO. The traditional 3-layer layeredArchitecture() rule (Args -> Json -> Api) was attempted first and rejected on evidence: json parsers/ serializers genuinely depend on root-package DTOs (Pair, ChatMessage, ContentPart) AND the root API genuinely depends on json parsers (LlamaIterator, JsonParameters, LlamaModel, ModelParameters import from json). json and api are peers in the public API layer, not a stackable hierarchy. Splitting the DTOs into a dedicated net.ladenthin.llama.value package would enable real layering, but breaks published public-API FQNs (net.ladenthin.llama.Pair, etc.) and is out of scope for an ArchUnit rule. The argsPackageIsALeaf rule pins the only real layered invariant that the current package design supports. noPackageCycles already catches the looser "no cycles between subpackages" property. Tests: 10 of 10 pass (was 9; +1 for the new leaf rule).
A complete sweep of src/main and src/test for every
net.ladenthin.llama.* system property the library understands, with
each property's default value and concrete consumer attached. The
previous README table covered only 5 of the 9 properties (the 4
test-only nomic + vision properties were undocumented in user-facing
docs) and described the 5 it did cover as "all resolved by
LlamaSystemProperties" - which the scan showed to be incorrect.
README changes:
- Replaces the 5-row "System Properties Reference" table with a 9-row
table covering every net.ladenthin.llama.* property the library
understands. Columns added: Default value, Scope (runtime vs test),
and Consumer (which production class or test class reads the
property). Test-only properties (nomic.path, vision.model,
vision.mmproj, vision.image) and the runtime-but-tests-also (test.ngl)
are now visible to users without having to read CLAUDE.md or grep
the source.
- "All ... resolved by LlamaSystemProperties" claim corrected: only
runtime properties go through the registry, and even there two
inconsistencies exist (see CLAUDE.md TODO).
- Adds the MultimodalIntegrationTest self-skip note so users
understand a partial vision setup still loads.
CLAUDE.md changes:
- The "Optional models" mini-table now cross-links to the README
reference instead of being the only place the 4 test-only properties
are documented. Mini-table kept (model paths + the issue numbers
it regresses) since that's deeper context than the README needs.
- New TODO entry flags the two source-side inconsistencies the scan
surfaced:
(1) LlamaSystemProperties.getLibName() is declared but zero
production callers reach it - either wire it into LlamaLoader's
filename-resolution path or delete it as dead code;
(2) OSInfo.java:390 reads "net.ladenthin.llama.osinfo.architecture"
directly via the literal string, bypassing the registry's
getOsinfoArchitecture() getter. Same single-source-of-truth
smell as the recent BAF Radix.HEX consolidation; routing OSInfo
through the registry getter is a small follow-up.
Deep-scan inventory (9 properties total):
Runtime (resolved via LlamaSystemProperties, with caveats above):
net.ladenthin.llama.lib.path -> LlamaLoader:92
net.ladenthin.llama.lib.name -> (declared, zero callers)
net.ladenthin.llama.tmpdir -> LlamaLoader:250
net.ladenthin.llama.osinfo.architecture -> OSInfo:390 (literal, bypasses registry)
Test (declared in TestConstants):
net.ladenthin.llama.test.ngl -> 8 test classes via Integer.getInteger
net.ladenthin.llama.nomic.path -> LlamaEmbeddingsTest
net.ladenthin.llama.vision.model -> MultimodalIntegrationTest
net.ladenthin.llama.vision.mmproj -> MultimodalIntegrationTest
net.ladenthin.llama.vision.image -> MultimodalIntegrationTest
No source / test changes; doc-only commit.
…hitecture()
OSInfo.getArchName() read the override system property via a hard-coded
string literal:
String override = System.getProperty("net.ladenthin.llama.osinfo.architecture");
bypassing LlamaSystemProperties.getOsinfoArchitecture(), the registry-side
getter built specifically to be the single source of truth for that
property name. The deep scan that produced the README System Properties
Reference (e36f631) surfaced this as one of two registry-bypass smells;
fixing it here closes the first.
Routing through the registry keeps the property name in exactly one
place, mirrors the recent BAF Radix.HEX consolidation (where every
literal '16' radix was replaced by a single Radix.HEX constant), and
means future renames or scope tightenings of the property only have to
land in LlamaSystemProperties.
Tests: OSInfoTest 16/16 pass (the override-set branch is already
covered by the test that sets ARCH_OVERRIDE_PROP); mvn compile clean.
…tLibName() Deep forensic comparison against kherud/java-llama.cpp (the upstream) showed that net.ladenthin.llama.lib.name has been a documentation-only ghost since 2023: Upstream history of "lib.name": c8f57f7 (initial JNI commit) - Javadoc mention AND real code consumer: String nativeLibName = System.getProperty("de.kherud.llama.lib.name"); if (nativeLibName == null) { ... } 7a852d1 - README documents it (-Dde.kherud.llama.lib.name=myname.so) 6bb63e1 ("add ggml shared library to binding") - CODE CONSUMER DELETED. The loader was extended to load multiple shared libraries (ggml and jllama as separate files); the single-name-override model became incompatible. Javadoc + README mentions were left behind. 6d0c4af - README mention removed. The Javadoc lie in LlamaLoader.java survives upstream to this day. Bernard's fork inherited the Javadoc lie verbatim and later added a LlamaSystemProperties.getLibName() getter for "completeness" (every documented property gets a registry getter) - but the loader code still hardcodes "jllama" and ignores the override. Why delete rather than re-wire: - Upstream deliberately removed the consumer to support multi-library loading. Re-wiring would either reintroduce the same single-name limitation upstream removed, or need a new design covering both libraries. - This fork has added even more dimensions (CPU / CUDA / OpenCL-Adreno classifiers); the "one override filename" idea is even less applicable now than in upstream's day. - No caller has ever asked for it; the README will be more honest with one fewer documented-but-broken row. Changes: - LlamaSystemProperties.getLibName() deleted (~5 lines). - LlamaLoader.java Javadoc fixed: lib.name removed from the "set these properties" sentence; replaced with a multi-paragraph history note citing upstream commit 6bb63e1 so future readers understand the property's lifecycle and don't try to "re-add" it. - README System Properties Reference: lib.name row dropped (was 9 rows, now 8). - CLAUDE.md: the registry-cleanup TODO is closed for both subitems (lib.name DELETED here; osinfo.architecture FIXED in 3ae6c81 by routing OSInfo.getArchName() through the registry getter). Tests: OSInfoTest 16/16 + LlamaLoaderTest 21/21 = 37/37 pass. mvn compile clean.
Emits a single info-level summary line at the end of every non-streaming
generation (complete / chat), mirroring what the llama.cpp CLI prints:
prompt: 12 tok in 84.3 ms (142.4 tok/s) | gen: 256 tok in 5031.7 ms (50.9 tok/s) | cache: 0
Speculative-decoding runs append:
| draft: 50 (35 accepted)
Implementation:
- New TimingsLogger utility class with two public methods:
format(Timings) -> single-line String (exposed so CLI sinks can reuse)
log(Timings) -> emits format(...) at INFO on
net.ladenthin.llama.timings (dedicated logger so
users can suppress it via logback without touching
the rest of net.ladenthin.llama).
- log() is a no-op for null and for all-zero Timings (typical on parse
failure / early cancellation). No noise from non-event paths.
- Wired into both result parsers right after the Timings instance is
built:
json/CompletionResponseParser#parseCompletionResult
json/ChatResponseParser#parseResponse
- Tests: 7 unit tests in TimingsLoggerTest pin the format byte-exact for
the standard case, draft segment presence/absence, cache-hit
rendering, dedicated-logger SLF4J pipeline delivery, all-zero
no-op, and null no-op. Uses LogCaptor (the same harness LoggingSmokeTest
uses for OSInfo).
Streaming generation (LlamaIterable / LlamaIterator) is not yet hooked.
The streaming iterator does not surface a clean "I am done" callback
visible from the public API today; threading that through is a separate
follow-up. Non-streaming covers the most common code path and gives
users an immediate signal.
The remaining first-batch items from the feature-investigation backlog
in CLAUDE.md are now the UTF-8 boundary-safe streaming decoder and a
jbang single-file example.
Tests run (per the test-execution policy — no full surefire):
- mvn compile / mvn test-compile: clean.
- mvn test -Dtest='TimingsLoggerTest': 7/7 pass.
- mvn test -Dtest='CompletionResponseParserTest,ChatResponseParserTest,
LoggingSmokeTest,LlamaArchitectureTest': 58/58 pass (covers both
parser wire-in sites plus the architecture invariants).
Move CLAUDE.md "Open TODOs" content into a dedicated TODO.md so CLAUDE.md keeps its role as orientation / build-commands / architecture, and TODO.md becomes the single per-repo home for open work and DONE history. TODO.md splits open work into: - jllama-specific: upstream feature exposure (skip_download is DONE, --spec-draft-backend-sampling / reasoning control / max_outputs / MtP / suppress_tokens are queued by policy), the similar-projects feature backlog, the GraalVM Native Image evaluation - cross-cutting slice: jqwik pin, @VisibleForTesting audit, null-safety follow-up, SpotBugs effort=Max, additional ArchUnit rules - Done history: the full strictness-ladder + workspace-migration trail (Werror, Checker, module-info @NullMarked, LogCaptor, setSkipDownload, LlamaSystemProperties cleanup, etc.) CLAUDE.md "Open TODOs" section now carries only a pointer to TODO.md and to workspace/crossrepostatus.md. Cross-repo coordination: each of the 4 sibling repos does the same extraction in this session. https://claude.ai/code/session_01LzoKmqzgtQsELS5tsH4Wog
Cross-repo decision to use Lombok at the latest version for compile-time generation of equals/hashCode/toString without runtime reflection. See BAF commit 31eb6ef for the full decision record. `<scope>provided</scope>` keeps Lombok off the runtime classpath; `requires static lombok;` in module-info.java keeps it compile-time only. The new lombok.config pins the standard cross-repo settings (addLombokGeneratedAnnotation, callSuper = call, stopBubbling). This commit is dependency-only. Per-class @tostring / @EqualsAndHashCode adoption is deferred until after the BAF restoration loop concludes and the user reviews the BAF approach. https://claude.ai/code/session_01LzoKmqzgtQsELS5tsH4Wog
Two badge-row changes in the Build section: 1. Add Lombok 1.18.46 badge between Maven Enforcer and jqwik — mirroring BAF (c7bfbc4) and plugin (38a8fdb) so all three repos that use Lombok carry the badge at the same slot. 2. Promote the [llama.cpp #b9495] badge from its previous slot (after JMH, near the end of the Build row) to row 3, right under Java + Platform. The pinned upstream version is the single most defining attribute of a JNI binding to llama.cpp, so a reader scanning the top of README needs to see it immediately — not buried after the testing/benchmarking tool badges. New ordering: Java -> Platform -> llama.cpp #b9495 -> JPMS -> JUnit -> JSpecify ... streambuffer keeps its hand-written toString and does NOT adopt Lombok, so the badge does NOT apply there. https://claude.ai/code/session_01LzoKmqzgtQsELS5tsH4Wog
…n sources Apply the BAF/plugin Lombok migration pattern to java-llama.cpp. Value-shaped types get @tostring + @EqualsAndHashCode; mutable lifecycle handles and operational classes get @tostring only (identity is the correct equals semantics); classes with semantically-meaningful handwritten toString implementations keep their custom toString and gain @EqualsAndHashCode only. Build wiring fixes (mirrors BAF/plugin): - pom.xml: add Lombok to <annotationProcessorPaths> AND extend the explicit -processor argument list to include both Lombok SPI processors (AnnotationProcessorHider$AnnotationProcessor and $ClaimingProcessor) alongside the existing Checker Framework NullnessChecker. - lombok.config: switch callSuper default from "call" to "skip" since most value classes extend Object directly. Value types (Lombok @tostring + @EqualsAndHashCode): - Pair, ChatChoice, ChatResponse, ContentPart, ToolDefinition Value types with derived/aggregated toString fields: - Usage (totalTokens via @ToString.Include on the getter) - TokenLogprob (topLogprobs rendered as size via @ToString.Include) - Timings (full field dump) Value types with semantically-meaningful handwritten toString preserved (@EqualsAndHashCode only, toString documented as intentional): - ChatMessage ("role: content" conversation-trace format) - ToolCall ("name(args)[id]" function-call syntax) - CompletionResult, LlamaOutput (return generated text verbatim — public API contract) - ModelMeta, ServerMetrics (re-serialise to compact JSON for assertEquals) - JsonParameters (emits actual JSON the native server consumes) - CliParameters (emits CLI argv-style string for the native binary) Subclasses of JsonParameters/CliParameters get @EqualsAndHashCode(callSuper=true): - InferenceParameters, ModelParameters Operational / lifecycle classes (Lombok @tostring only; identity-equals is correct; native handles and lambdas excluded from rendered output): - LlamaModel (parser collaborators rendered, native ctx handle visible) - LlamaIterator, LlamaIterable, LlamaPublisher (owning model excluded — recursive native-state dump) - Session (model + lambdas + lock excluded) - CancellationToken, ChatRequest (lambdas excluded) - LlamaLoader, LlamaSystemProperties, NativeLibraryPermissionSetter, ProcessRunner, Java8CompatibilityHelper Test update: - PairTest.testHashCodeMatchesObjectsHash renamed and rewritten to verify the hashCode contract (non-zero, varies by field) rather than pinning to Objects.hash. The PIT-mutation-killing intent is preserved but no longer assumes the specific implementation. Intentionally skipped (rationale documented inline): - OSInfo — vendored from sqlite-jdbc with explicit "only deviations" policy; adding Lombok would diverge further. Spotless line-wrapping is incidental. - LlamaException, ModelUnavailableException — extend Throwable, which already provides toString and identity-equals. - StopReason, LogLevel — enums, inherit toString from Enum. - LoadProgressCallback, ToolHandler — interfaces. - SkipDownloadFailureTranslator, TimingsLogger — non-instantiable utility classes (private constructor + all-static methods). All 888 runnable tests pass; the single RerankingModelTest error is a pre-existing UnsatisfiedLinkError on this sandbox (no native library built in restricted-network env, per CLAUDE.md). https://claude.ai/code/session_01LzoKmqzgtQsELS5tsH4Wog
Lombok-generated equals / hashCode / canEqual / toString carry the textbook polynomial-hash pattern (int result = 1; result = result * 59 + ...; return result;) which fb-contrib's USBR detector reads at the bytecode level as a store-then-immediate-return. SpotBugs core already skips its own detectors on members carrying @lombok.Generated (emitted by lombok.config's lombok.addLombokGeneratedAnnotation = true), but fb-contrib runs as a separate plugin family and does not honour that annotation. A method- name-based <Match> covers every member Lombok can emit. Clears 18 jllama findings at SpotBugs Max+Low. The collateral cost is small: any handwritten equals/hashCode/toString that genuinely stores-then-immediately-returns is either a debugger-friendly local- variable pattern or a micro-optimisation, both intentional here. https://claude.ai/code/session_01LzoKmqzgtQsELS5tsH4Wog

Defers the 25-site scope-tightening pass until after the planned package-architecture refactor. Same rationale and decision recorded in workspace/crossrepostatus.md alongside the parallel BAF suppression. Why suppress instead of fix now: - Current jllama package layout groups production code in net.ladenthin.llama + a thin sibling package set. Any method called only by same-package callers is flagged as "could be package-private". Correct today, false tomorrow once the refactor splits the root package into proper layers — cross-layer calls then need public. - Tightening every site now creates mechanical churn the refactor would revert. - TODO marker added to workspace/crossrepostatus.md under the "Affects BAF + jllama (multi-package repos)" section so the rule can be re-enabled deliberately the week the layers stabilise. Cross-repo alignment: same suppression added to BAF (BitcoinAddressFinder/spotbugs-exclude.xml, 33 sites there).
…x+Low row OPM_OVERLY_PERMISSIVE_METHOD is now project-wide suppressed (07109cc) pending the package-architecture refactor. The TODO row now describes the remaining ~65 findings (DRE 20, WEM 14 + low-count residue) plus adds the lifecycle TODO to re-enable the rule when the layered package structure stabilises — same shape as BAF's matching entry.
…l signatures LlamaException extends RuntimeException (LlamaException.java:18), so the 20 'throws LlamaException' declarations on LlamaModel are unchecked exceptions in throws clauses — the canonical DRE_DECLARED_RUNTIME_EXCEPTION fb-contrib pattern. JDK convention is to advertise unchecked exceptions via Javadoc @throws only, never the throws clause. Sites (all in LlamaModel.java): - 4 Java methods: completeAsJson (2 overloads), getMetricsTyped, getModelMeta - 16 native methods: requestCompletion, receiveCompletionJson, loadModel, loadModelWithProgress, handleRerank, handleCompletions, handleCompletionsOai, handleInfill, handleEmbeddings, handleTokenize, handleDetokenize, getModelMetaJson, configureParallelInference, handleSlotAction, handleChatCompletions, requestChatCompletion The existing '@throws LlamaException' Javadoc tags were preserved on every site (verified at lines 65, 69, 90, 525, 540, 644, 737, 755, 773, 793) so javadoc:jar still documents the unchecked exception contract for callers. Compatibility audit: - Public API: callers either catch LlamaException explicitly (works without the throws declaration), declare it in their own throws (overrides can throw fewer or unchecked), or don't catch (still propagates unchecked). Zero caller-side break. - Native bridge: JNI throws via ThrowNew regardless of the Java throws clause — no JNI-side enforcement of the clause. - Tests: 888 of 889 tests pass; the 1 error is an unrelated UnsatisfiedLinkError because this sandbox has no built native library (documented in CLAUDE.md as a known mvn-test-without-cmake failure mode), not caused by this change. - mvn javadoc:jar -DskipTests=true -Dgpg.skip=true: BUILD SUCCESS. SpotBugs Max+Low: DRE_DECLARED_RUNTIME_EXCEPTION goes 20 → 0. Total jllama findings: 65 → 45. Top remaining: WEM 14, UVA 5, MDM_WAIT_WITHOUT_TIMEOUT 4, THROWS_METHOD_THROWS_RUNTIMEEXCEPTION 4.
…leared)
Switches 4 ModelParameters setter validations to typed
IllegalArgumentException with in-scope state, clearing 4 WEM and 2
THROWS_METHOD_THROWS_RUNTIMEEXCEPTION findings in one pass (the two
THROWS_METHOD sites overlapped with WEM on setRepeatLastN and
setDryPenaltyLastN, which previously threw bare RuntimeException).
Sites:
- setPriority : message now includes value + allowed range
0=normal 1=medium 2=high 3=realtime
- setPriorityBatch : same shape
- setRepeatLastN : bare RuntimeException -> IllegalArgumentException;
message includes value + "must be >= -1; -1 =
ctx_size, 0 = disabled"
- setDryPenaltyLastN : bare RuntimeException -> IllegalArgumentException;
message includes value + "must be >= -1; -1 =
context size, 0 = disabled"
Test consistency cleanup (ModelParametersTest):
- Lines 101, 122 tightened from assertThrows(RuntimeException.class,
...) to assertThrows(IllegalArgumentException.class, ...) to match the
4 sibling tests at 49, 54, 69, 74 that already assert the specific
type. The narrower assertion is strict-compatible: the prior assertion
would also pass since IllegalArgumentException extends RuntimeException.
Compatibility:
- ModelParameters is final (line 21) — no subclass override risk.
- Callers catching RuntimeException continue to catch the new
IllegalArgumentException unchanged.
- Builder chain return-type unchanged.
Test slice green: 288 tests across ModelParametersTest (62),

Adds in-scope state (slotId + transcript size) to the 5 state-machine
IllegalStateException messages thrown by Session.send / stream /
commitStreamedReply / save / restore.
Before:
throw new IllegalStateException(
"stream in progress; call commitStreamedReply(...) before send(...)");
After:
throw new IllegalStateException(
"stream in progress on slot " + slotId
+ " (transcript=" + turns.size() + " turns)"
+ "; call commitStreamedReply(...) before send(...)");
Why both fields:
- slotId identifies which session got stuck in a multi-session setup
(a process can hold many Sessions on the same model, one per slot).
- turns.size() shows how far the transcript progressed before the
state-machine violation — useful when triaging "the session went
weird around message N" reports.
Compatibility:
- Session is final (line 41) — no subclass override risk.
- No test asserts on the exception message text (verified across
SessionConcurrencyTest, LlamaModelTest).
THROWS_METHOD_THROWS_RUNTIMEEXCEPTION findings on Session.send and
Session.stream (the catch+cleanup+rethrow pattern at line 112 / 138)
are deliberately NOT addressed in this batch; they are deferred to
their own investigation alongside the existing BAF suppression
(spotbugs/spotbugs#3918 + PR #4087 lifecycle).

Batch 4 — leaf-class WEM (5 sites):
- ChatMessage.requireNonEmpty: message now distinguishes
null vs size=0 input
- ChatRequest.setMaxToolRounds: message now includes the
rejected value
- ContentPart.imageBytes: message now includes bytes.length so the
operator knows which call failed
- LlamaLoader.getNativeResourcePath: message now includes the active
classLoader so the operator can debug class-loading issues
- LlamaPublisher.subscribe: message now references reactive-streams
§1.9 and includes the calling thread name (the spec rule citation
helps callers, the thread name is the WEM runtime expression)
Batch 5 — UVA array → varargs (5 sites):
- InferenceParameters.setPenaltyPrompt(int[]) -> int...
- LlamaModel.decode(int[]) -> int...
- LlamaModel.decodeBytes(int[]) -> int... (native)
- LlamaModel.handleDetokenize(int[]) -> int... (native)
- ParameterJsonSerializer.buildIntArray(int[]) -> int...
Varargs is source-compatible with all existing array call sites; the
new call shape f(1, 2, 3) is additionally allowed. Bytecode signature
stays [I with the ACC_VARARGS bit flipped on — JNI doesn't enforce
the bit, so native method signatures are unchanged on the C side.
Test impact (LlamaPublisherTest.nullSubscriberThrows):
- Previously: assertEquals("subscriber", ...) — exact-match assertion.
- Now: assertTrue(msg.startsWith("reactive-streams §1.9: subscriber
must not be null"), ...) — prefix-match so the runtime thread-name
suffix doesn't break the assertion across environments.
Test slice green: 162 tests across ChatMessageTest (2),
ChatRequestTest, ContentPartTest (14), LlamaLoaderTest (21),
LlamaPublisherTest (4), InferenceParametersTest (86),

…dapters Removes the hand-rolled reactive-streams Publisher and the associated mandatory runtime dependency on org.reactivestreams. Adds consumer-facing documentation showing how to wrap LlamaIterable with each mainstream reactive library's resource-management primitive — verified end-to-end by a new ReactorIntegrationTest using test-scope reactor-core. Why now ======= LlamaPublisher (introduced in PR #188 as section 2.3 of the Kotlin SDK feature comparison) had zero non-test callers. The feature-investigation document itself describes its source spec as "no longer a roadmap". The real-world Android consumer LLaMAndroid uses the existing LlamaIterable API directly inside a Kotlin flow { } block — bypassing the publisher entirely. Upstream kherud/java-llama.cpp never carried this class. LlamaIterable already implements Iterable<LlamaOutput> + AutoCloseable — the contract every reactive library needs to bridge a blocking source: - Project Reactor : Flux.using(supplier, Flux::fromIterable, ::close) - RxJava 3 / RxAndroid : Flowable.using(supplier, Flowable::fromIterable, ::close) - Kotlin Flow : flow { iterable.use { for (x in it) emit(x) } } - Akka Streams : Source.fromIterator(() -> iterable.iterator()) These are the canonical patterns the libraries themselves recommend for blocking sources. Keeping a Publisher in the binding forced every consumer onto the org.reactivestreams runtime dep just to access a class nobody called. Critical correctness note: Flux.fromIterable / Flowable.fromIterable do NOT auto-close AutoCloseable iterables on cancel — the consumer must use .using(...) or equivalent. The README documents this caveat explicitly; the ReactorIntegrationTest pins the correct pattern. Changes ======= Deletes: - src/main/java/net/ladenthin/llama/LlamaPublisher.java (175 LOC) - src/test/java/net/ladenthin/llama/LlamaPublisherTest.java (204 LOC) - LlamaModel.streamPublisher / streamChatPublisher (23 LOC) - pom.xml org.reactivestreams runtime dep + version property - module-info.java javadoc reference Adds: - src/test/java/net/ladenthin/llama/ReactorIntegrationTest.java Mock-iterable contract test (always runs) + real-model gate test proving end-to-end cancel propagation via Flux.using + LlamaIterable.close - pom.xml reactor-core + reactor-test at test scope, 3.6.11 - README.md new "Reactive integration" section covering Reactor, RxJava 3, Kotlin Flow (with LLaMAndroid reference), Akka Streams, and the why-no-built-in-Publisher rationale Updates: - docs/feature-investigation-llama-stack-client-kotlin.md: section 2.3 status now reads "SHIPPED + REVERTED REACTIVE PUBLISHER" with full rationale and pointer to the README - TODO.md: new Done entry capturing the decision trail Net: -331 LOC (-503 source, +172 test/docs); -1 runtime dep (org.reactivestreams); +2 test-scope deps (reactor-core, reactor-test). SpotBugs Max+Low: total drops 25 -> 19 (all 6 LlamaPublisher$LlamaSubscription findings cleared as a side effect: MDM_WAIT_WITHOUT_TIMEOUT x4 + CWO_CLOSED_WITHOUT_OPENED + PRMC_POSSIBLY_REDUNDANT_METHOD_CALLS). Tests ===== ReactorIntegrationTest: 2 tests, mock variant always runs, real-model variant gated on TestConstants.MODEL_PATH. Mock test proves Reactor backpressure (request(2) delivers exactly 2 items, never more) and cleanup-on-cancel (Flux.using cleanup function fires on cancel). 887 of 888 tests pass (the 1 error is the known sandbox-without-native-lib UnsatisfiedLinkError in RerankingModelTest, unrelated to this change).
NullAway and the package's @NullMarked declaration prove the three getters (ChatMessage.getContent, ToolCall.getArgumentsJson, ToolDefinition.getDescription) are @nonnull at compile time, so the runtime "value == null ? "" : value" ternaries and the "if (getDescription() != null)" guard at three sites in buildMessagesJson / buildToolsJson are dead. Also narrows the catch in buildToolsJson from Exception to IOException. The only checked exception MAPPER.readTree(String) can throw is JsonProcessingException, which extends IOException — narrowing is honest and removes the catch-Exception code smell. Adds: import java.io.IOException. Compatibility: - Empty-string output on a null content/arguments is impossible per NullAway, so removing the fallback never changes runtime behaviour. - The 7 tests in ChatResponseTest (including buildMessagesJsonRoundTripsToolTurns and buildToolsJsonInlinesParameterSchema, which exercise both modified code paths) stay green. SpotBugs Max+Low: - RCN_REDUNDANT_NULLCHECK_OF_NONNULL_VALUE: 4 -> 1 (ChatMessage.requireNonEmpty:103 remains, separate cluster) - REC_CATCH_EXCEPTION: 1 -> 0 Total jllama: 19 -> 15.
… cleared) The parts parameter is typed List<ContentPart> (no @nullable); the package is @NullMarked so NullAway proves the value cannot be null at the check site. The 'parts == null ||' branch and the ternary '(parts == null ? "null" : "size=0")' branch are dead code. After removal: - Single guard: if (parts.isEmpty()) - Message keeps a runtime expression (parts.size()) so the WEM requirement satisfied in Batch 4 stays satisfied. Compatibility: - requireNonEmpty is private static — only called from ChatMessage constructors in the same @NullMarked package, so NullAway's proof covers every caller statically. - No test asserts on the message text. SpotBugs Max+Low: RCN_REDUNDANT_NULLCHECK_OF_NONNULL_VALUE 1 -> 0. Total jllama: 15 -> 14.
…tics Removes the single use of Checker Framework's @polynull qualifier in production code (JsonParameters.toJsonString). Under @NullMarked, the elegant @polynull contract (null in → null out, non-null in → non-null out) is not expressible in plain JSpecify, so the prior shape required @SuppressWarnings("NullAway") and forced fb-contrib to flag AI_ANNOTATION_ISSUES_NEEDS_NULLABLE (which it does not understand @polynull). The cleanup splits the helper and routes the 7 user-facing setters through a new null-aware put method: toJsonString(String text) Serialize a NON-NULL text to JSON form. Used directly by the two enum-driven setters (setReasoningFormat, setContinueFinalMessage) where the input is always non-null. putOptionalJson(String key, @nullable String text) Conditionally store: when text is null the call is a no-op, otherwise the value is JSON-encoded and inserted. Used by the seven user-facing setters (setPrompt, setInputPrefix, setInputSuffix, setGrammar, setPenaltyPrompt, setChatTemplate, setToolChoice). Behaviour: setX(null) now omits the key from the parameters map instead of inserting a null value entry. On the native side (nlohmann::json) both a missing key and a null-valued key signal "use the default", so the observable behaviour is preserved. The single test that exercises this (InferenceParametersTest .testToJsonStringNull) continues to pass — its assertion (parameters.get("grammar") returns null) is satisfied identically by absence as it was by a null-value entry. Also removes the now-unused org.checkerframework.checker.nullness.qual .PolyNull import, leaving the production-code Checker Framework footprint at exactly 2 lines, both deliberate @SuppressWarnings("method.invocation") on LlamaModel constructors that call native loadModel — required because Checker's @UnderInitialization analysis cannot see that the native callee does not dereference this. SpotBugs Max+Low: AI_ANNOTATION_ISSUES_NEEDS_NULLABLE 1 -> 0. Total jllama: 14 -> 13. All 93 tests across InferenceParametersTest (86) and ChatResponseTest (7) green; the modified setters and the JSON build path are both covered.
…ce to Optional<String> Brings the codebase to 100% on the established "nullable getters return Optional<T>" convention (CLAUDE.md / TODO.md note: "Public-API methods that may legitimately have no value use Optional<T> rather than @nullable T"). Migrated: - ChatMessage.getToolCallId() : @nullable String -> Optional<String> - ChatRequest.getToolChoice() : @nullable String -> Optional<String> Updated callers (using the project's existing .ifPresent idiom): ChatRequest.buildMessagesJson (was): final String toolCallId = m.getToolCallId(); if (toolCallId != null) { obj.put("tool_call_id", toolCallId); } After: m.getToolCallId().ifPresent(id -> obj.put("tool_call_id", id)); LlamaModel.requestChatCompletion (was): final String toolChoice = request.getToolChoice(); if (toolChoice != null) { params.setToolChoice(toolChoice); } After: request.getToolChoice().ifPresent(params::setToolChoice); StopReason.getStopType() was DELIBERATELY NOT migrated. It is paired with StopReason.fromStopType(@nullable String) in a round-trip test: assertSame(reason, StopReason.fromStopType(reason.getStopType())); Switching the getter to Optional<String> would force the test caller to do reason.getStopType().orElse(null), which defeats the purpose. The factory takes @nullable per the project convention (Optional as parameter is anti-idiom per Effective Java §55), and the symmetric getter follows. Remaining @nullable T return types in production: - JsonParameters.toJsonString : private helper, kept as @nullable (call sites use the new putOptionalJson method instead) - StopReason.getStopType : paired with @nullable factory - ParameterJsonSerializer.buildMessages : internal Jackson builder - Timings.fromJson : factory, takes @nullable JsonNode Tests: 95 green across ChatMessageTest, ChatResponseTest, ChatAdvancedTest, InferenceParametersTest. No test asserted on @nullable String return shape of either migrated getter.
… Session Eliminates the catch-cleanup-rethrow pattern in Session.send and Session.stream by moving transcript management into a new ChatTranscript class whose API surface enforces the two-phase commit invariant by construction. The catch-rethrow pattern fb-contrib flagged (THROWS_METHOD_THROWS_RUNTIMEEXCEPTION) was the symptom of "mutate shared state, then if the call fails, undo the mutation". The ChatTranscript design eliminates the root cause: there is no API to commit half a round. The only round-commit method, appendRound(user, assistant), appends both turns atomically; the wire format sent to the model is built via messagesWithPendingUserTurn(...) which returns a fresh list WITHOUT mutating the transcript. On model failure, the caller never reaches appendRound — no rollback logic is required. Side benefit — testable as running documentation. Extracting the transcript management decouples the invariant from LlamaModel (whose static initializer loads the native library and is unmockable in test environments without the native library). The new ChatTranscriptTest exercises the invariant with 12 tests across two categories: @nested "mechanical API behaviour" (8 tests): - appendRound commits both turns atomically - appendUserTurn + appendAssistantTurn match appendRound - messagesWithPendingUserTurn does NOT mutate the transcript - messagesWithPendingUserTurn returns a fresh list each call - snapshot includes the system message when configured - snapshot omits the system message when null or empty - snapshot is unmodifiable - getSystemMessage returns null when absent @nested "two-phase commit pattern - running documentation" (4 tests): - fresh transcript untouched when model throws - existing transcript byte-for-byte unchanged when model throws - success commits user + assistant atomically - stream() shape - user turn only, assistant follows via commitStreamedReply Each two-phase test composes the ChatTranscript API the same way Session.send and Session.stream do, so reading the test doubles as documentation of the design contract. Net: - New file: src/main/java/net/ladenthin/llama/ChatTranscript.java - New file: src/test/java/net/ladenthin/llama/ChatTranscriptTest.java - Session.java: 247 lines -> 247 lines (no net change; delegates to ChatTranscript). The catch-rethrow blocks are gone; the buildParamsWithPendingUserTurn helper now delegates to ChatTranscript.messagesWithPendingUserTurn. SpotBugs Max+Low: - THROWS_METHOD_THROWS_RUNTIMEEXCEPTION goes 2 -> 0 by design, not by suppression. Cross-repo lifecycle TODO for BAF (PR #4087) can take inspiration from this refactor on AbstractProducer.produceKeys if/when that two-phase commit fits. - IMC_IMMATURE_CLASS_NO_EQUALS goes 2 -> 3 (one new finding on the new ChatTranscript class — identity-by-design like the existing CancellationToken and ChatRequest sites; will fold into the existing class-level suppression block). Total jllama: 13 -> 12. Test slice green: 117 tests across ChatTranscriptTest (12), ChatMessageTest (2), ChatResponseTest (7), InferenceParametersTest (86), LlamaArchitectureTest (10).
Convert ChatRequest from a mutable fluent builder into a fully immutable
value class with a functional "wither / appender" API:
ChatRequest.empty()
.appendMessage("user", "hi")
.withMaxToolRounds(2)
.withInferenceCustomizer(p -> p.setSeed(1));
Each modification routes through a single private all-args constructor
with one field replaced, allocating a new ChatRequest. The original is
never touched, so a caller can safely hold an intermediate request and
derive variants without hidden state changes.
Notable side effect: this fixes a hidden mutation bug in
LlamaModel.chatWithTools(). The previous agent loop mutated the caller's
ChatRequest across rounds (adding the assistant turn + each tool result
to the same builder). The loop is now rebound to a local `current` that
is replaced on every append, preserving the caller's request.
Tests:
- New ChatRequestTest documents the immutability + value-equality
contract in 18 cases across four @nested groups (immutability,
equality, validation, JSON-build read-only).
- LlamaModelTest and ChatResponseTest call sites migrated from
`new ChatRequest()...addMessage(...)` to
`ChatRequest.empty()...appendMessage(...)`.
SpotBugs:
- IMC_NO_EQUALS goal cleared at source (the class is now a true value
object with Lombok @EqualsAndHashCode by value).
- EI_EXPOSE_REP on getMessages()/getTools() suppressed with explicit
rationale: the fields ARE Collections.unmodifiableList views; the
test suite verifies that mutation attempts throw
UnsupportedOperationException, so the finding is a false positive.
Commit f97c85d (spotbugs RCN cleanup) removed the null branch inside requireNonEmpty under the assumption that the JSpecify @nonnull default made parts==null unreachable. The deliberately type-cast call site in MultimodalMessagesTest.nullPartsListIsRejected bypasses that static check at compile time, so the runtime path now NPEs inside requireNonEmpty(parts).isEmpty() instead of throwing the documented IllegalArgumentException. Restore the contract by validating null at the public-constructor boundary (the right place for external-input validation) and keep the private requireNonEmpty focused on the empty case.
Convert InferenceParameters from a mutable fluent builder into a fully
immutable value class with a functional wither API:
InferenceParameters params = InferenceParameters.of("two plus two?")
.withNPredict(8)
.withSeed(1)
.withTemperature(0.2f);
The parent JsonParameters base is reshaped to match: parameters map is
final and Collections.unmodifiableMap-wrapped, and the helpers
putScalar / putEnum / putOptionalJson are replaced by withScalar /
withEnum / withOptionalJson / withRaw, all of which allocate a new
subclass instance through the abstract withParameters(Map) factory
hook. ModelParameters extends a different parent (CliParameters) and
is unchanged — it is constructed once and consumed once, so the
immutability refactor brings no correctness payoff there but ~250 test
line changes; deliberately skipped to keep this commit focused.
Hidden mutation bug fixed: LlamaModel.complete /
completeWithStats / chatComplete and the cancellable complete-with-token
variant silently called parameters.setStream(true|false) on the
caller's instance. They now bind a local derivation via withStream so
the caller's parameters object is never touched. Same pattern applied
to LlamaIterator.
API breaks (intentional, alongside the parameter rename):
- Consumer<InferenceParameters> -> UnaryOperator<InferenceParameters>
in Session and ChatRequest. The customiser must return its
transformed result because the input is immutable; lambdas like
`p -> p.withSeed(1).withNPredict(8)` keep working with the
expression-form return.
- ChatRequest.applyCustomizer now returns InferenceParameters instead
of being a void mutator; callers (only LlamaModel.chat) updated.
Tests:
- JsonParametersTest rewritten to cover the new wither helpers
(withScalar / withEnum / withRaw / withOptionalJson) plus the
unmodifiable-map invariant. The legacy CliParameters putScalar /
putEnum tests are preserved unchanged because ModelParameters still
uses them.
- Bulk-renamed setX -> withX across the entire test surface
(InferenceParametersTest 71+, ChatAdvancedTest 84, LlamaModelTest 90,
ChatScenarioTest 64, MemoryManagementTest 40, plus smaller files and
all examples), preserving ModelParameters' fluent setX chains where
the overlap methods (setSeed, setGrammar, setJsonSchema, setSamplers,
setChatTemplate, setChatTemplateKwargs, setReasoningFormat) appear.
- A handful of tests that did `params.setX(...)` without capturing the
return value were rewritten to `params = params.withX(...)`.
SpotBugs Max+Low: net unchanged at 6 findings. The one new
OCP_OVERLY_CONCRETE_PARAMETER on InferenceParameters.withReasoningFormat
is suppressed with the same design-intent rationale as the existing
ModelParameters OCP block (the narrow enum type is the API contract;
widening to CliArg would silently accept any enum and emit a nonsense
JSON value).
Set lombok.equalsAndHashCode.doNotUseGetters = true and lombok.toString.doNotUseGetters = true in lombok.config so Lombok- generated equals/hashCode/toString read fields directly instead of routing through `this.getX()`. Motivation: several value classes expose getters that wrap their `@Nullable T` field in Optional<T> (ChatRequest.getToolChoice, ChatMessage.getToolCallId) or wrap a list field in Collections.unmodifiableList + Optional (ChatMessage.getParts) for the public-API contract. Those wrappers are not the equality contract. The previous getter-routing behaviour caused two real defects: 1. fb-contrib OI_OPTIONAL_ISSUES_CHECKING_REFERENCE fired on every Lombok-generated `this$x == null` branch when the getter returned an Optional. Optional is the standard "never null" type, so the null arm was dead code — fb-contrib correctly flagged it, contradicting my prior characterisation as a "false positive". 2. ChatMessage.getParts() allocated a fresh Collections.unmodifiableList AND a fresh Optional on every equals or hashCode call. With field access these allocations disappear entirely. Switching is semantically identical: Optional.equals and Collections.unmodifiableList(x).equals(...) both delegate to value- based comparison of the underlying state. Verified by an audit covering every Lombok-annotated class: - Bucket 1 (verbatim getter): 11 classes — bit-identical output. - Bucket 2 (Optional/unmodifiable wrapper getter): ChatRequest, ChatMessage — both benefit from the switch. - Bucket 3 (getter does non-trivial work equality should see): 0. - Bucket 4 (@ToString-only identity classes): unaffected. All value classes are `final`, so subclass-override of a getter cannot change equality. callSuper=true chains (InferenceParameters/ModelParameters) are unaffected because the parent classes have no getter on their own included field. No test in the repository pins a Lombok-format `Class(field=value)` substring. SpotBugs Max+Low: 6 -> 2 findings (the 4 OI_OPTIONAL_ISSUES_CHECKING_REFERENCE entries on ChatRequest/ChatMessage equals + hashCode clear). The remaining 2 findings (DLS_DEAD_LOCAL_STORE on cancelHook, SPP_FIELD_COULD_BE_STATIC on LlamaModel.ctx) are pre-existing and unrelated. Full test suite: 921 tests pass (the 1 error is the environmental RerankingModelTest.setup UnsatisfiedLinkError — no native library on this sandbox — not a regression).
…USBR + getter routing)
End-to-end sweep that brings jllama to zero SpotBugs Max+Low findings.
The history audit while doing this surfaced that several earlier
"successful" suppressions were lost in past rebases and never actually
committed — this commit re-applies the canonical pattern in one place.
Five changes:
1. DLS_DEAD_LOCAL_STORE on LlamaModel.completeAsync — Option A from the
cross-repo discussion: drop the `cancelHook` local entirely, lift
`@SuppressWarnings("FutureReturnValueIgnored")` to the method. The
inline comment documents why the suppression sits at method scope
(cross-repo FireAndForget DLS reckoning).
2. SPP_FIELD_COULD_BE_STATIC on LlamaModel.ctx — narrow `<Match>` block
in spotbugs-exclude.xml with rationale: `ctx` is the per-instance
native handle, making it static would corrupt state across parallel
LlamaModel instances.
3. RCN_REDUNDANT_NULLCHECK_OF_NONNULL_VALUE x2 in ChatRequest.buildMessagesJson:
ChatMessage.getContent() and ToolCall.getArgumentsJson() are both
@nonnull (no @nullable annotation; NullAway proves the contract);
the `== null ? "" : ...` ternaries were dead code. Removed.
4. USBR_UNNECESSARY_STORE_BEFORE_RETURN on Lombok-generated equals /
hashCode / canEqual / toString — restore the cross-repo canonical
suppression block. Lombok injects the textbook polynomial-hash
pattern (`int result = 1; ...; return result;`) on every value
class; fb-contrib's USBR detector doesn't honour @lombok.Generated
and would otherwise fire ~18 times across the codebase. Suppression
matches the four Lombok-emitted method names; the cross-repo
rationale lives in ../workspace/policies/lombok-config.md.
5. lombok.config — restore `doNotUseGetters = true` for
@EqualsAndHashCode and @tostring. Cross-repo invariant tracked in
the workspace policy. Without it, fb-contrib
OI_OPTIONAL_ISSUES_CHECKING_REFERENCE fires on every Optional-
wrapping getter routed through Lombok's generated equals/hashCode
(ChatMessage.getParts() returns Optional<List<ContentPart>>).
Verification:
- mvn compile spotbugs:check -Dspotbugs.effort=Max -Dspotbugs.threshold=Low
→ BugInstance size is 0, BUILD SUCCESS.
- 121 tests pass across ChatRequestTest / ChatResponseTest /
InferenceParametersTest / JsonParametersTest / MultimodalMessagesTest.
Net cross-repo SpotBugs Max+Low: 0 / 0 / 0 / 0 across jllama / BAF /
plugin / streambuffer.
