zerodds-java-omgdds v1.0 — Spec Coverage

Audit of the vendor spec docs/specs/zerodds-java-omgdds-1.0.md against the crates/java-omgdds/ code reality.

Source: docs/specs/zerodds-java-omgdds-1.0.md (vendor spec, 2026-05-06).

Context: the implementation is a plain Maven Java module inside the crates directory; it contains no Rust code:

§1 Architecture

§1.1 Module layout

Spec: §1.1 — a Java source tree under crates/java-omgdds/java/src/main/java/ with org/omg/dds/* (normative API) and org/zerodds/internal/* (implementation detail).

Repo: 510 Java files (378 under src/main, 132 under src/test; counted with find crates/java-omgdds/java/src -name "*.java"). - org/omg/dds/core/ (26 files, plus core/policy/ with 28 files and the packages core/event, core/status) - org/omg/dds/topic/ (13 files) - org/omg/dds/sub/ (15 files) - org/omg/dds/pub/ (9 files) - org/omg/dds/domain/ (7 files) - org/omg/dds/** in total 184 files - org/zerodds/… (194 files, among them crates/java-omgdds/java/src/main/java/org/zerodds/internal/InProcessBus.java, crates/java-omgdds/java/src/main/java/org/zerodds/internal/Xcdr2Codec.java, bridge/GrpcBridgeClient.java) - 132 test files in src/test/ - the Maven pom in crates/java-omgdds/java/pom.xml

Tests: crates/java-omgdds/java/src/test/java/org/omg/dds/QuickstartApiTest.java::serviceEnvironmentBootstrapBySystemProperty (boots the surface across org/omg/dds/**) plus the 128 test classes Maven collects from src/test/java: 940 tests, 1 skipped. Invocation: mvn -B -Pjava8 clean verify in crates/java-omgdds/java, as in the job endpoints-java-async. The directory holds no Rust code — there is no Cargo.toml and hence no cargo test.

Status: done

§1.2 InProcessBus

Spec: §1.2 — a thread-safe topic map, push-based sample delivery to all DataReaders on the same topic.

Repo: crates/java-omgdds/java/src/main/java/org/zerodds/internal/ InProcessBus.java.

Tests: crates/java-omgdds/java/src/test/java/org/omg/dds/PubSubLoopbackTest.java::singleWriterSingleReaderRoundTrip, crates/java-omgdds/java/src/test/java/org/omg/dds/PubSubLoopbackTest.java::readReturnsSamplesWithoutRemoving, crates/java-omgdds/java/src/test/java/org/omg/dds/PubSubLoopbackTest.java::multipleReadersAllReceiveSample, crates/java-omgdds/java/src/test/java/org/omg/dds/PubSubLoopbackTest.java::cleanupRemovesSubscription.

Status: done

§1.3 Xcdr2Codec

Spec: §1.3 — a Java-native XCDR2 encoder/decoder, spec-conformant per DDS-XTypes 1.3 §7.4.

Repo: org/zerodds/internal/Xcdr2Codec.java.

Tests: crates/java-omgdds/java/src/test/java/org/omg/dds/Xcdr2CodecTest.java::primitivesRoundTrip, crates/java-omgdds/java/src/test/java/org/omg/dds/Xcdr2CodecTest.java::utf8StringRoundTrip, crates/java-omgdds/java/src/test/java/org/omg/dds/Xcdr2CodecTest.java::multipleStringsRoundTrip, crates/java-omgdds/java/src/test/java/org/omg/dds/Xcdr2CodecTest.java::shortAlignmentSkipsByte.

Status: done

§2 OMG API coverage

Status: done

§2.3 org.omg.dds.topic.*

Spec: §2 — Topic + TopicTypeSupport.

Repo: crates/java-omgdds/java/src/main/java/org/omg/dds/topic/Topic.java + crates/java-omgdds/java/src/main/java/org/zerodds/cdr/TopicTypeSupport.java.

Tests: crates/java-omgdds/java/src/test/java/org/omg/dds/PubSubLoopbackTest.java::singleWriterSingleReaderRoundTrip, crates/java-omgdds/java/src/test/java/org/omg/dds/QuickstartApiTest.java::singleArgFactoryReflectsTypedBean (the TypeSupport is derived from the topic).

Status: done

§2.4 org.omg.dds.pub.*

Spec: §2 — Publisher + DataWriter.

Repo: crates/java-omgdds/java/src/main/java/org/omg/dds/pub/Publisher.java + crates/java-omgdds/java/src/main/java/org/omg/dds/pub/DataWriter.java.

Status: done

§2.6 org.omg.dds.core.policy.*

Spec: §2 — QosProfile (default-QoS path, optional XML-QoS loader).

Repo: crates/java-omgdds/java/src/main/java/org/omg/dds/core/QosProvider.java, crates/java-omgdds/java/src/main/java/org/zerodds/core/qos/QosProviderImpl.java.

Tests: crates/java-omgdds/java/src/test/java/org/omg/dds/QosLifecycleTest.java::historyKeepLastCapsPerInstance, crates/java-omgdds/java/src/test/java/org/omg/dds/QosLifecycleTest.java::transientLocalReplaysToLateJoiner, crates/java-omgdds/java/src/test/java/org/omg/dds/QosLifecycleTest.java::exclusiveOwnershipArbitratesToHighestStrength, crates/java-omgdds/java/src/test/java/org/omg/dds/QosLifecycleTest.java::partitionIsolatesNonOverlappingEndpoints, crates/java-omgdds/java/src/test/java/org/omg/dds/QosLifecycleTest.java::requestedDeadlineMissedIsRaised, crates/java-omgdds/java/src/test/java/org/omg/dds/QosLifecycleTest.java::livelinessRxoKindAndLease, crates/java-omgdds/java/src/test/java/org/omg/dds/QosLifecycleTest.java::rxoIncompatibleReliabilityDetected — one test per policy class in org/omg/dds/core/policy/ (History, Durability, Ownership, Partition, Deadline, Liveliness, Reliability); 21 tests in the class overall.

Status: done — the default-QoS path is live; the XML-QoS loader is tracked in the zerodds-xml-1.0 audit file (separate spec).

§3 Test requirement

§3.1 mvn test green

Spec: §3 — mvn test must run green.

Repo: crates/java-omgdds/java/pom.xml with a JUnit 5 setup.

Tests: the Maven Surefire run covers 123 test classes; the widest of them is crates/java-omgdds/java/src/test/java/org/omg/dds/QuickstartApiTest.java::byteArrayQuickstartRoundTrip. Measured (mvn test in crates/java-omgdds/java): Tests run: 925, Failures: 0, Errors: 0, Skipped: 3 (log /root/agent-java/logs/xt-bind-1018-070634.log on the Linux test host).

Status: done

§4 Multi-process / cross-vendor

§4.1 Pure-Java + gRPC-bridge decision

Spec: §4 — the pure-Java path has no RTPS wire stack. The single-JVM path via InProcessBus; multi-JVM and cross-vendor run over the gRPC bridge to the zerodds-grpc-bridged daemon (§5, implemented).

Repo: crates/java-omgdds/java/ (pure-Java with InProcessBus). An earlier JNI bridge was removed; its crate is no longer in the tree.

Tests: single-JVM path — crates/java-omgdds/java/src/test/java/org/omg/dds/PubSubLoopbackTest.java::singleWriterSingleReaderRoundTrip. Multi-JVM path — crates/java-omgdds/java/src/test/java/org/zerodds/bridge/GrpcBridgeClientTest.java::publishThenSubscribeRoundtripThroughDds (env-gated on ZERODDS_BRIDGE_PORT; skipped in the default run, the only skip of the module, declared in ci/declared-skips.tsv). That the tree now goes beyond the §4 statement is measured by crates/java-omgdds/java/src/test/java/org/zerodds/rtps/RtpsWireTest.java::twoParticipantsExchangeSampleOverUdp.

Status: done — the routing decision of vendor-spec §4 (single-JVM over InProcessBus, multi-JVM over the gRPC bridge) is implemented and proven. Deviation from the spec prose: org/zerodds/rtps/ now carries a pure-Java RTPS stack (SPDP/SEDP/DATA over UDP) that vendor-spec §6 schedules for v2.0; the §4 phrase “no RTPS wire stack” describes the v1.0 surface, not today’s tree.

§4.2 gRPC bridge for multi-process

Spec: §5 — the gRPC service exposes DDS publish/subscribe (zerodds.bridge.v1.<topic>/Publish|Subscribe), a pure-Java client connects.

Repo: daemon zerodds-grpc-bridged (service routing in service_gen.rs, /zerodds.bridge.v1.<topic>/Publish|Subscribe) + pure-Java h2c client org/zerodds/bridge/GrpcBridgeClient.java (raw HTTP/2 + HPACK + protobuf Sample/PublishAck — no grpc-java, no TLS, Java-8 compatible).

Tests: crates/java-omgdds/java/src/test/java/org/zerodds/bridge/GrpcBridgeClientTest.java::protobufSampleRoundtrips, crates/java-omgdds/java/src/test/java/org/zerodds/bridge/GrpcBridgeClientTest.java::publishAckDecodes (codec self-checks, always run), crates/java-omgdds/java/src/test/java/org/zerodds/bridge/GrpcBridgeClientTest.java::publishThenSubscribeRoundtripThroughDds (a real Java-gRPC-DDS roundtrip via crates/java-omgdds/run_grpc_bridge_e2e.sh, env-gated on ZERODDS_BRIDGE_PORT; skipped in the default run).

Status: done — multi-JVM path implemented + e2e-proven.

Goal — zero-copy via the Foreign Memory API

Spec: Goals — “NativeAOT-friendly: Java 22 MemorySegment/Foreign-Memory-API (v1.1) for zero-copy without JNI.”

Repo: —

Tests: —

Status: open — crates/java-omgdds/ contains neither MemorySegment nor any other call of the Foreign Memory API.

§5 Stability

§5 Semver promise — v1.0 = the current surface

Spec: §6 — semver: v1.0 = the current surface (pure-Java with InProcessBus); v1.1 = + gRPC bridge; v2.0 = + pure-Java RTPS.

Repo: crates/java-omgdds/java/pom.xml (the module version).

Tests: crates/java-omgdds/java/src/test/java/org/omg/dds/QuickstartApiTest.java::serviceEnvironmentBootstrapBySystemProperty, crates/java-omgdds/java/src/test/java/org/omg/dds/QuickstartApiTest.java::byteArrayQuickstartRoundTrip, crates/java-omgdds/java/src/test/java/org/omg/dds/QuickstartApiTest.java::singleArgFactoryReflectsTypedBean, crates/java-omgdds/java/src/test/java/org/omg/dds/QuickstartApiTest.java::getDataAliasesData — the class calls the documented v1.0 surface by name; renaming or removing a type breaks the compilation of the test module.

Status: done

Gemessen (mvn test in crates/java-omgdds/java): Tests run: 925, Failures: 0, Errors: 0, Skipped: 3 (Log /root/agent-java/logs/xt-bind-1018-070634.log auf dem Linux-Testhost).

Status: done

§4 Multi-Process / Cross-Vendor

§4.1 Pure-Java + gRPC-Bridge Decision

Spec: §4 — Der Pure-Java-Pfad hat keinen RTPS-Wire-Stack. Single-JVM-Pfad via InProcessBus; Multi-JVM und Cross-Vendor laufen über die gRPC-Bridge zum zerodds-grpc-bridged-Daemon (§5, implementiert).

Repo: crates/java-omgdds/java/ (Pure-Java mit InProcessBus). Eine frühere JNI-Bridge wurde entfernt; ihre Crate ist nicht mehr im Baum.

Tests: Single-JVM-Pfad — crates/java-omgdds/java/src/test/java/org/omg/dds/PubSubLoopbackTest.java::singleWriterSingleReaderRoundTrip. Multi-JVM-Pfad — crates/java-omgdds/java/src/test/java/org/zerodds/bridge/GrpcBridgeClientTest.java::publishThenSubscribeRoundtripThroughDds (env-gated über ZERODDS_BRIDGE_PORT; im Default-Lauf übersprungen, der einzige Skip des Moduls, deklariert in ci/declared-skips.tsv). Dass der Baum inzwischen über die §4-Aussage hinausgeht, misst crates/java-omgdds/java/src/test/java/org/zerodds/rtps/RtpsWireTest.java::twoParticipantsExchangeSampleOverUdp.

Status: done — die Routing-Entscheidung der Vendor-Spec §4 (Single-JVM über InProcessBus, Multi-JVM über die gRPC-Bridge) ist implementiert und belegt. Abweichung zur Spec-Prosa: org/zerodds/rtps/ trägt inzwischen einen Pure-Java-RTPS-Stack (SPDP/SEDP/DATA über UDP), den Vendor-Spec §6 erst für v2.0 vorsieht; die §4-Aussage „kein RTPS-Wire-Stack” beschreibt die v1.0-Surface, nicht den heutigen Baum.

§4.2 gRPC-Bridge für Multi-Process

Spec: §5 — gRPC-Service exponiert DDS Publish/Subscribe (zerodds.bridge.v1.<Topic>/Publish|Subscribe), Pure-Java-Client verbindet sich.

Repo: Daemon zerodds-grpc-bridged (Service-Routing service_gen.rs, /zerodds.bridge.v1.<Topic>/Publish|Subscribe) + Pure-Java-h2c-Client org/zerodds/bridge/GrpcBridgeClient.java (raw HTTP/2 + HPACK + protobuf Sample/PublishAck — kein grpc-java, kein TLS, Java-8-kompatibel).

Tests: crates/java-omgdds/java/src/test/java/org/zerodds/bridge/GrpcBridgeClientTest.java::protobufSampleRoundtrips, crates/java-omgdds/java/src/test/java/org/zerodds/bridge/GrpcBridgeClientTest.java::publishAckDecodes (Codec-Self-Checks, laufen immer), crates/java-omgdds/java/src/test/java/org/zerodds/bridge/GrpcBridgeClientTest.java::publishThenSubscribeRoundtripThroughDds (echter Java-gRPC-DDS-Roundtrip via crates/java-omgdds/run_grpc_bridge_e2e.sh, env-gated über ZERODDS_BRIDGE_PORT; im Default-Lauf übersprungen).

Status: done — Multi-JVM-Pfad implementiert + e2e-belegt.

Ziel — Zero-Copy über die Foreign-Memory-API

Spec: Ziele — „NativeAOT-friendly: Java 22 MemorySegment/Foreign-Memory-API (v1.1) for zero-copy without JNI.“

Status: open — crates/java-omgdds/ enthält weder MemorySegment noch einen anderen Aufruf der Foreign-Memory-API.

§5 Stabilität

§5 Semver-Zusage — v1.0 = aktuelle Surface
