Update all Micronaut Platform 5.2 projects to Micronaut Core 5.2

[dstepanov]

Tracking issue for moving every project managed by the Micronaut Platform 5.2 onto Micronaut Core 5.2.x (latest: 5.2.0, released 2026-09-10; the platform catalog still pins 5.1.14).

Progress: 40/71 projects on core 5.2 · 69/71 tested against 5.2 (54 ✅ pass · 15 ⚠️ issues found · 0 ❌ open core regression · 0 ⏳ running)

For each project:

1. Merge a core 5.2.x bump on its active branch.
2. Test it against core 5.2.x.
3. Fix any regressions in core or in the module.

Legend: ⬜ not on core 5.2 yet · ✅ on core 5.2 · Test column: ✅ passes · ⚠️ issues found (fixed or module-side) · ❌ open core regression · ⏳ running · — not tested yet

Core under test: 5.2.x at c6158f9 (5.2.1-SNAPSHOT, includes the fixes below) or the equivalent 5.2.0 release code. Core issues found so far:

• Iterate the introspections in a stable order again #13096: iterate introspections in a stable order again (broke micronaut-data H2 tests)
• Keep a property's annotations to the type it is read through #13099: keep a property's annotations to the type it is read through (broke serde @JsonIgnoreProperties inheritance)
• /metrics management endpoint of released micronaut-micrometer 6.0.2 (compiled against core 5.1) returns 404 on core 5.2, which breaks micronaut-sql DataSourcePoolMetadataSpec, 6 micronaut-kafka metrics specs and 2 micronaut-eclipsestore metrics specs. Bisected to Enumerate beans by their @Indexed types even when not implemented #12960 (d44e268, enumerate beans by their @Indexed types); fix in Find beans compiled before their annotation was self-indexed #13111
• Only look up introspections in a class loader that shares the core types #13109: only look up introspections in a class loader that shares the core types (breaks micronaut-oracle-cloud oraclecloud-function-http; verified 27/27 with the fix)
• micronaut-validation Jakarta TCK: 32 failures on core 5.2 (constraint inheritance, group sequences, cross-parameter validators, property paths); passes 384/384 on core 5.1.11. Bisected to Add the micronaut-reflection module #12977 (2c9161c, add the micronaut-reflection module); investigation session running; fix in Serve the registered annotation type to a caller naming no class loader #13114 (verified: TCK 384/384)
• Jackson 3.1.4 → 3.2.2 (managed by core 5.2): java.net.InetAddress no longer deserializes from a hostname. This breaks micronaut-discovery-client Consul registration (15 tests) and serde's InetAddressTest (databind variant adapted in Update to Micronaut Core 5.2 micronaut-serialization#1415; serde's InetAddressSerde still resolves hostnames, pending this decision). Decide whether core keeps 3.2.2 (and modules adapt, e.g. keep the address as a String or configure the deserializer) or pins or configures Jackson — proposed module-side fix: Keep Consul addresses as the strings Consul sends micronaut-discovery-client#897 keeps Consul addresses as strings (no DNS in deserialization), so core can keep Jackson 3.2.2 Merged (discovery-client#897 on 5.2.x).
• micronaut-hibernate-validator: Hibernate constraint validators (e.g. @URL on String) are no longer found by DefaultValidator when a @Validated bean is created on core 5.2 (ValidatedBeanSpec, 3/7; 7/7 on core 5.1.1). It uses the released micronaut-validation 5.0.0. Bisected to fix: allow validated @Value constructor params without @Introspected #12859 (aeded4f, allow validated @value constructor params without @introspected); investigation session running; fix in Validate injected values with Hibernate Validator micronaut-hibernate-validator#598 (against 5.1.x)
• Argument.equalsType no longer matches a Kotlin Map<String, Any> (or other out-variance) argument against Argument.mapOf(String, Object): since Compile a wildcard type argument to a WildcardArgument that keeps its bounds #13023 the nested ? extends Object is a WildcardArgument, DefaultArgument.equalsType compares type parameters with equals, and DefaultWildcardArgument.equals rejects a plain argument. This breaks micronaut-rabbitmq @RabbitHeaders (Kotlin docs HeadersSpec) at runtime, and Compile a wildcard type argument to a WildcardArgument that keeps its bounds #13023 intended equalsType to ignore bounds — fix Compare nested type arguments by type in equalsType and typeHashCode #13115

Module-side follow-ups:

• micronaut-data: NullAway errors on Reactor 3.8 @Nullable block() in BlockingReactorRepositoryOperations and SynchronousConnectionOperationsFromReactiveConnectionOperations
• micronaut-serialization: update 6 test-suite-tck-jackson-databind expectations for Jackson 3.2, in Update to Micronaut Core 5.2 micronaut-serialization#1415 (core 5.2.0 bump on 3.2.x at 3.2.0-SNAPSHOT, cbor 3.2.2). The databind variant runs the 3 conflicting @JsonTypeInfo cases with EXISTING_PROPERTY through a base-spec hook, expects {} for class-level NON_DEFAULT null, and replaces InetAddressTest with a no-DNS DatabindInetAddressSpec. It also drops the now-passing @PendingFeature and CompoundLocaleObjectMapperListener. Serde's own behaviour is unchanged. check passes on 5.2.x c6158f9e0e; on 5.2.0 only SerdeJsonIgnoreAllowSpec inheritance fails (Keep a property's annotations to the type it is read through #13099); review requested
• micronaut-servlet: add micronaut-management to the HTTP server TCK suites; CorsSimpleRequestTest and SimpleRequestWithCorsNotEnabledTest call /refresh since Use management refresh endpoint in CORS TCKs #12880 (30 failures). Servlet parity, waves 1 and 2: multipart, body-less requests, JDK server, request cleanup micronaut-servlet#1123 excludes SimpleRequestWithCorsNotEnabledTest on POJA but doesn't add the dependency, and it re-enables CorsSimpleRequestTest on Jetty; its CI is pending
• micronaut-servlet: update the Jetty, Tomcat and Undertow error specs and Jetty FilterErrorSpec for micronaut.server.error-response-include-message (default never), done in Servlet parity, waves 1 and 2: multipart, body-less requests, JDK server, request cleanup micronaut-servlet#1123
• micronaut-kafka: AbstractTestContainersSpec.stopContext (kafka-streams) calls getBean on a context that is no longer running, which throws IllegalStateException since Throw IllegalStateException when resolving beans from a context that is not running #12948 and fails UncaughtExceptionsSpec.cleanupSpec; fix in Fix kafka tests failing on Micronaut Core 5.2 micronaut-kafka#1397
• micronaut-session: Kotlin docs example ShoppingControllerTest.kt needs !! or safe calls after blockFirst() (Reactor 3.8 @Nullable), fix in Assert non-null on blockFirst() in the Kotlin docs example micronaut-session#381
• micronaut-views: update FreemarkerViewRendererSpec for micronaut.server.error-response-include-message (default never), fix and core 5.2.0 bump in Fix Freemarker error message test for core 5.2 and update core to 5.2.0 micronaut-views#1190 (on the unreleased 6.3.x)
• micronaut-jaxrs: map the new HttpMethod.QUERY (Add RFC 10008 support (QUERY Method) #12780) in jaxrs-processor HttpMethodMapper to @Query; a plain default branch compiles but QUERY requests get 405. Fix in Map the QUERY HTTP method to Micronaut's @Query micronaut-jaxrs#677 (against 5.1.x, builds on core 5.1 and 5.2)
• micronaut-problem: when shouldIncludeErrorMessageAsDetailForDefaultProblem is enabled, take the detail from ErrorContext.getExceptionMessage(); core 05421f2 removed the message from the default error message (DataLeakageOverrideSpec) — fix micronaut-problem-json#568: rebuilds the detail from the root cause (5.1.x compiles against core 5.1.3, which has no getExceptionMessage()); check passes on 5.1.3 and 5.2.0
• micronaut-sourcegen: test-suite-kotlin HeronTest should expect 2 Heron.Boo values from getAnnotationValuesByType and re-enable the bam assertion; core 5.2 now resolves both repeatable annotations, fix in Expect both repeated @Heron.Boo values in the Kotlin HeronTest (needs core 5.2) micronaut-sourcegen#511. Note: it targets 2.2.x, whose 2.2.0 is released, and passes only on core 5.2; it belongs on a new 2.3.x minor
• micronaut-security: update BuiltInEndpointsSpec for the new micronaut.server.error-response-include-message setting, which defaults to never (core 05421f2) and removes the exception message from 500 responses, fix in Accept the 500 body without the exception message in BuiltInEndpointsSpec micronaut-security#2277

Proposed core 5.2.1 patch release

Several 5.2 projects fail only because of core regressions. All of them are now fixed on 5.2.x. A core 5.2.1 release with these fixes unblocks them without changes in the projects. Verification publishes core from 5.2.x, then reruns the previously failing tests of each affected project against it (--rerun, with test counts read from the XML reports).

Merged into 5.2.x since 5.2.0

All known core regressions are merged into 5.2.x (last: #13111 on 2026-09-11). Core 5.2.1 can be released.

Bump PRs waiting for the 5.2.1 release:

• Update Micronaut dependencies micronaut-oracle-cloud#1371 (needs Only look up introspections in a class loader that shares the core types #13109)
• Update Micronaut dependencies micronaut-validation#684 (needs Serve the registered annotation type to a caller naming no class loader #13114)
• the rabbitmq core 5.2 bump on its new minor (needs Compare nested type arguments by type in equalsType and typeHashCode #13115)
• sql, kafka and eclipsestore core 5.2 bumps (need Find beans compiled before their annotation was self-indexed #13111; verified on 5.2.x head 6d53fc7bb4)

Not fixed by a core patch

• micronaut-hibernate-validator ValidatedBeanSpec (fix: allow validated @Value constructor params without @Introspected #12859, @Value beans skip validateBean): still fails 3/3 on fc92af42a4. The fix is module-side: Validate injected values with Hibernate Validator micronaut-hibernate-validator#598, merged on 5.1.x; the 5.2.x core bump Fix subproject name so IntelliJ Gradle integration doesn't complain #599 is merged and green.
• Jackson 3.2 InetAddress hostnames → micronaut-discovery-client Consul registration: Keep Consul addresses as the strings Consul sends micronaut-discovery-client#897, merged on 5.2.x; the Renovate core 5.2 bump Update Micronaut dependencies micronaut-discovery-client#887 needs a branch update to pick it up.
• Deliberate core 5.2 changes that need module updates, already merged: security#2277, views#1190, problem-json#568, jaxrs#677, session#381 and kafka#1397.
• Still open: serialization#1415 (Jackson 3.2 TCK expectations), servlet#1123, azure/gcp server TCK (azure#1020 merged, gcp#1538 open), test-resources#1212, data (Reactor 3.8 NullAway), and sourcegen (HeronTest repeatable-annotation count).

Core 5.2 must land in a new minor

Core 5.2 may only be merged into a new, unreleased minor of each library: the target branch must be at X.Y.0-SNAPSHOT, and no vX.Y.* release may exist yet. Patch branches of released minors must stay on core 5.1.

Merged into a released minor, so these need moving to a new minor branch (revert on the patch branch, re-apply on X.(Y+1).x):

Projects not on the correct new minor branch

40/71 done: core 5.2 on a new, unreleased minor branch (X.Y.0-SNAPSHOT, newer than the latest release) that is also the default branch, so Renovate and the common-files sync target it. Remaining projects, by what is left:

The last one, PublisherExceptionHandlerTest, was a connection reset under local load. A module-side fix task has been spawned; CI on micronaut-projects/micronaut-azure#1018 is still pending. Fix PR: micronaut-projects/micronaut-azure#1020 (function TCK suites).
⬜	micronaut-cache	6.2.x ✅	6.1.1	5.1.14	micronaut-projects/micronaut-cache#1055 → 5.2.0	✅	6.2.x, core c6158f9e0e. 200 tests, 0 failed. Fix PRs: micronaut-projects/micronaut-cache#1064 (audit on 6.2.x) and micronaut-projects/micronaut-cache#1065 (stop publishing a strict jackson-core constraint).
✅	micronaut-cassandra	7.2.x ✅	7.1.0	5.2.0	micronaut-projects/micronaut-cassandra#666 → 5.2.0 (merged)	✅	7.1.x, core c6158f9e0e. 22 tests, 0 failed (on commit caa5f1d, the core 5.2 bump that micronaut-projects/micronaut-cassandra#666 re-applies on the new 7.2.x).
✅	micronaut-chatbots	2.2.x ✅	2.1.0	5.2.0	micronaut-projects/micronaut-chatbots#425 → 5.2.0 (merged)	✅	653 tests, 0 failed
✅	micronaut-coherence	7.1.x ✅	7.0.1	5.2.0	micronaut-projects/micronaut-coherence#1059 → 5.2.0 (merged)	—	Not tested locally: the run was stopped after 106m with 0 test results; the Coherence system session never starts (SafeCluster restart loop, InjectorImplTest initializationError), a local cluster networking issue. Needs CI or a baseline run.
⬜	micronaut-control-panel	2.2.x ✅	2.1.0	5.1.12	micronaut-projects/micronaut-control-panel#659 → 5.2.0	⚠️	2.2.x. 263 tests, 0 failed, but three tasks fail dependency resolution before running: :micronaut-control-panel-ui:test and the doc example's inspectRuntimeClasspath and playwrightInstall. jackson-core cannot be resolved because micronaut-cache-infinispan 6.1.1 publishes {strictly 2.21.4} and micronaut-object-storage-gcp 3.1.0 publishes 2.18.9. It fails the same way in CI on micronaut-projects/micronaut-control-panel#659, and on 2.2.x since the move to cache 6.1.1 (not caused by the bump). Only cache-infinispan's strictly conflicts. Fixes: micronaut-projects/micronaut-control-panel#661 against 2.2.x (component metadata rule that relaxes the strict pin; jackson-core resolves to 2.22.1, 290 tests with 1 local Oracle container timeout), and root cause micronaut-projects/micronaut-cache#1065 against 6.1.x (plain constraint instead of strictly).
✅	micronaut-crac	3.2.x ✅	3.1.0	5.2.0	micronaut-projects/micronaut-crac#544 → 5.2.0 (merged)	✅	36 tests, 0 failed (1 skipped)
⬜	micronaut-data	5.2.x ✅	4.14.5	5.1.12	micronaut-projects/micronaut-data#4035 → 5.2.0	⚠️	5.2.x, core snapshot. data-model and data-connection fail to compile: Reactor 3.8 marks block() @Nullable and NullAway treats that as an error, so data needs a fix. H2 tests (753): JdbcRepositorySpec failed intermittently because of introspection order, fixed in #13096.
⬜	micronaut-discovery-client	5.2.x ✅	5.1.0	5.1.7	micronaut-projects/micronaut-discovery-client#887 → 5.2.0	⚠️	5.2.x, core c6158f9e0e. 218 tests, 15 failed, all with one cause: the Consul client tests (ConsulMockAutoRegistrationSpec ×9, ConsulClientSpec, ConsulMockHealthStatusSpec, TtlHeartbeatSpec, CompositeDiscoverySpec, ClientScopeSpec) fail with InvalidFormatException: Cannot deserialize value of type java.net.InetAddress from String "<hostname>". Jackson 3.2.2, managed by core 5.2 (up from 3.1.4), no longer accepts a hostname for InetAddress. This affects Consul registration at runtime, not just tests. Baseline on core 5.1.7 (Jackson 3.1.x): 204 tests, 0 failed, so this comes from the Jackson upgrade. Fix: micronaut-projects/micronaut-discovery-client#897 (Consul addresses kept as strings; Consul tests and japiCmp pass on core 5.2.0 and 5.1.7). Update: fix micronaut-projects/micronaut-discovery-client#897 merged.
⬜	micronaut-eclipsestore	2.2.x	2.1.0	5.1.6	micronaut-projects/micronaut-eclipsestore#325 → 5.2.0	✅	2.1.x, core c6158f9e0e. 108 tests, 2 failed: EclipseStoreMetricsBinderSpec and EclipseStoreMetricsBinderDisabledSpec get 404 Not Found from /metrics, the same regression as micronaut-sql and micronaut-kafka (released micronaut-micrometer endpoint not routed, #12960, fix in #13111). Baseline on core 5.1.6: eclipsestore 21/21 with all 20 test classes selected. Update: core #13111 merged into 5.2.x (6d53fc7); both EclipseStoreMetricsBinder*Spec pass against core 5.2.x head 6d53fc7. Needs a core 5.2.1 release.
⬜	micronaut-elasticsearch	6.2.x	6.1.0	5.1.6	micronaut-projects/micronaut-elasticsearch#746 → 5.2.0	✅	6.1.x, core c6158f9e0e. 15 tests, 0 failed. Fix PR: micronaut-projects/micronaut-elasticsearch#745 (audit on 6.1.x).
✅	micronaut-email	3.3.x ✅	3.2.0	5.2.0	micronaut-projects/micronaut-email#653 → 5.2.0 (merged)	✅	3.2.x, core c6158f9e0e. 284 tests, 0 failed.
✅	micronaut-flyway	8.2.x ✅	8.1.1	5.2.0	micronaut-projects/micronaut-flyway#907 → 5.2.0 (merged)	✅	8.1.x, core c6158f9e0e. 32 tests, 1 failed: test-suite-oracle timed out starting the Oracle container ("DATABASE IS READY TO USE!" never logged), an environment issue that is not core related.
✅	micronaut-gcp	6.2.x ✅	6.1.0	5.2.0	—	⚠️	6.1.x. 778 tests, 18 failed, all in the two GCP Function HTTP server TCK suites; the 2 ErrorHandler* ones are local-load flakes. Fixed in micronaut-projects/micronaut-gcp#1538 → 6.2.x (6.2.x created from 6.1.x HEAD; the PR carries the fix, the cherry-picked bump and 6.2.0-SNAPSHOT). Not core: micronaut-management already comes through the TCK. (1) GcpFunctionHttpServerUnderTest forced endpoints.refresh.enabled=false, so /refresh was 404; now a default. (2) GoogleFunctionHttpRequest.getParameters() URL-decoded multipart/form-data, so force=true never bound (200, refresh count 0). That is a production bug too; form fields now come from getParts(), which the embedded test server and HttpFunction.invoke now provide. No TCK test excluded. Local, --rerun-tasks: TCK 235 + 246 tests on core 5.2.0 and 224 + 231 on 5.1.9, 0 failed; function module checks green.

✅	micronaut-hibernate-validator	5.2.x ✅	5.1.0	5.2.0	micronaut-projects/micronaut-hibernate-validator#599 → 5.2.0 (merged)	✅	5.1.x, core c6158f9e0e. 7 tests, 3 failed: ValidatedBeanSpec (invalid bean, custom validator, custom validator that is not a bean) fails with UnexpectedTypeException: Cannot find a constraint validator for constraint: org.hibernate.validator.constraints.URL and type: class java.lang.String, raised by DefaultValidator.validateConstrains during bean instantiation. The project uses released micronaut-validation 5.0.0. Baseline on core 5.1.1: 7/7 pass, so this is a core regression, bisected to #12859 (aeded4f). Update: not a core patch after all. The module-side fix micronaut-projects/micronaut-hibernate-validator#598 is merged on 5.1.x, and the core 5.2.0 bump micronaut-projects/micronaut-hibernate-validator#599 merged on the new 5.2.x with green CI.
✅	micronaut-jackson-xml	5.2.x ✅	5.1.0	5.2.0	micronaut-projects/micronaut-jackson-xml#569 → 5.2.0 (merged)	✅	5.1.x, core c6158f9e0e. 26 tests, 0 failed.

✅	micronaut-jaxrs	5.2.x ✅	5.1.0	5.2.0	micronaut-projects/micronaut-jaxrs#678 → 5.2.0 (merged)	⚠️	5.1.x, core 5.2.0. The only 5.2 break is HttpMethodMapper: the switch (httpMethod) is not exhaustive after HttpMethod.QUERY was added (#12780). A default branch alone compiles, but a JAX-RS @HttpMethod("QUERY") resource then gets 405, because a custom method route is never matched for a QUERY request. micronaut-projects/micronaut-jaxrs#677 maps it to @Query. With it, check passes on 5.2.0 and matches a 5.1.12 baseline (TCK 2,764 tests, 1,074 skipped). Still needs a new 5.2.x branch for the bump. AnnotationReflectionUtils.resolveGenericToArgument can then move to ReflectionArguments. DefaultHttpClient.setHandlerRegistry has no public replacement: DefaultHttpClientBuilder.handlerRegistry is package-private. Update: fix micronaut-projects/micronaut-jaxrs#677 merged.
✅	micronaut-jms	5.2.x ✅	5.1.0	5.2.0	micronaut-projects/micronaut-jms#780 → 5.2.0 (merged)	✅	5.1.x, core c6158f9e0e. 24 tests, 0 failed.

⬜	micronaut-kafka	6.2.x ✅	6.1.0	5.1.7	micronaut-projects/micronaut-kafka#1399 → 5.2.0	✅	6.2.x, core c6158f9e0e. 377 tests, 8 failed. 6 are the /metrics 404 of released micronaut-micrometer 6.0.2 (KafkaListenerSpec, KafkaConsumerMetricsSpec, KafkaProducerMetricsSpec, KafkaStreamsMetricsSpec ×2, KafkaStreamsMetricsDisabledSpec), caused by #12960. UncaughtExceptionsSpec fails in cleanupSpec: its shared stopContext calls getBean on a context that is no longer running, which throws IllegalStateException since #12948. KafkaClientSpec "send when Kafka is not available" got TimeoutException instead of ExecutionException, and it fails on core 5.1.7 too. Baseline on core 5.1.7: kafka 297 tests with only that 1 failure; kafka-streams 40/40. Follow-up 2026-09-10: all 6 metrics specs pass against core with #13111 (full check 376 tests, 1 failed: the Groovy docs MyTest, which also fails on 5.1.7 and is fixed in micronaut-projects/micronaut-kafka#1398). UncaughtExceptionsSpec (early return in stopContext) and KafkaClientSpec (a 1 s get racing a ~1 s producer failure) are fixed in micronaut-projects/micronaut-kafka#1397. The core bump waits for a core release that includes #13111. Update: fix micronaut-projects/micronaut-kafka#1397 merged. Update: core #13111 merged into 5.2.x (6d53fc7); the metrics specs pass (0 failed) against core 5.2.x head 6d53fc7. Needs a core 5.2.1 release.

The 2 failures (kubernetes-operator ConfigMapResourceReconcilerSpec and ConfigMapResourceReconcilerWithFiltersSpec, "Failed to resolve the apiGroup for V1ConfigMap from discovery cache") need a live cluster for API discovery, and they fail the same way on core 5.1.13 (16 tests, same 2 failures).

Fixed by #13109 (27/27 pass with it). The other failures are OCI config or pre-existing. Update: core #13109 is merged into 5.2.x (1154498); :micronaut-oraclecloud-function-http:test passes 27/27 (1 @PendingFeature skipped) against core 5.2.x head 1d17e8f. Needs a core 5.2.1 release.

⬜	micronaut-problem	5.1.x ✅	5.0.0	5.1.3	—	⚠️	5.1.x, core c6158f9e0e. 25 tests, 1 failed: DataLeakageOverrideSpec overrides shouldIncludeErrorMessageAsDetailForDefaultProblem and expects the detail "Internal Server Error: foo data", but gets "Internal Server Error". Core 05421f2 no longer includes the exception message in the error message by default (micronaut.server.error-response-include-message=never) and exposes it as ErrorContext.getExceptionMessage(), so micronaut-problem should build the detail from that.

ProductClient.send(@RabbitHeaders headers: Map<String, Any>) compiles to Map<String, ? extends Object>, which is now a WildcardArgument (#13023). DefaultArgument.equalsType compares nested type parameters with equals, and DefaultWildcardArgument.equals requires the other side to be a wildcard too, so argument.equalsType(Argument.mapOf(String.class, Object.class)) is false. It passes on core 5.1.11 (HeadersSpec 1/1 with Predictive Test Selection disabled). Core regression. Fix: #13115 (not fixed by #13109/#13111/#13114; control retest still fails).

BuiltInEndpointsSpec (sensitive endpoint without a SensitiveEndpointRule replacement) fails every time: the 500 response no longer includes the exception message, because core 05421f2 added micronaut.server.error-response-include-message with default never. The test needs updating. SecuredExpressionSpec was flaky and passes on rerun. Update: fix micronaut-projects/micronaut-security#2277 merged.
⬜	micronaut-serialization	3.2.x	3.1.1	5.1.3	micronaut-projects/micronaut-serialization#1415 → 5.2.0	⚠️	3.2.x, core snapshot. @JsonIgnoreProperties inheritance regression, fixed in #13099. 6 failures in test-suite-tck-jackson-databind come from Jackson 3.1.4 → 3.2.2. With micronaut-projects/micronaut-serialization#1415: check passes on 5.2.x c6158f9e0e (0 failures). On 5.2.0 only the SerdeJsonIgnoreAllowSpec inheritance case fails, fixed in 5.2.1 by #13099. test-suite-http-server-tck-netty is flaky locally (connection closed, a different test each run).
⬜	micronaut-servlet	6.2.x	6.1.0	5.1.3	micronaut-projects/micronaut-servlet#1123 → 5.2.0	⚠️	6.2.x, core c6158f9e0e. 1883 tests, 34 failed, all module-side. 28 are 7 CorsSimpleRequestTest tests × the Tomcat, Undertow, JDK and POJA-Apache TCK suites (refresh count 0): #12880 made the CORS TCK call the management /refresh endpoint, and servlet's TCK suites lack micronaut-management. 4 are the Jetty, Tomcat and Undertow *ErrorSpec streaming error tests and Jetty FilterErrorSpec, which expect the exception message that core 05421f2 now hides by default (micronaut.server.error-response-include-message=never). 2 are POJA-Apache SimpleRequestWithCorsNotEnabledTest 404s with the same cause: #12880 rewrote that test to call /refresh too. Baseline on core 5.1.3: all 34 of these pass.
✅	micronaut-session	5.2.x ✅	5.1.0	5.2.0	micronaut-projects/micronaut-session#380 → 5.2.0 (merged)	⚠️	5.2.x, core c6158f9e0e. 36 tests, 0 failed, but :micronaut-docs-examples:micronaut-example-kotlin:compileTestKotlin fails: ShoppingControllerTest.kt calls .body() and .header() on Flux...blockFirst(), which Reactor 3.8 (managed by core 5.2) marks @Nullable, so Kotlin types it HttpResponse<Cart>?. The docs example needs !! or safe calls. Same Reactor 3.8 nullability cause as micronaut-data; no core API change. It compiles on core 5.1.10 (Reactor 3.7). Update: session#381 is merged; Renovate rebased micronaut-projects/micronaut-session#380 onto it and build (25) now passes. build_matrix failed on an HTTP 500 from services.gradle.org and is being rerun.
⬜	micronaut-sourcegen	2.2.x	2.2.0	5.1.10	—	⚠️	2.2.x, core c6158f9e0e. 1550 tests, 1 failed: test-suite-kotlin HeronTest asserts getAnnotationValuesByType(Heron.Boo) returns 1, but core 5.2 returns 2. The test comment already says "There should actually be 2 Boo annotations", so this is core fixing repeatable annotation resolution. The test should expect 2 and re-enable the bam assertion. Baseline on core 5.1.10: test-suite-kotlin 68/68, so the change comes from core 5.2.
✅	micronaut-spring	6.2.x ✅	6.1.0	5.2.0	micronaut-projects/micronaut-spring#864 → 5.2.0 (merged)	✅	6.2.x, core c6158f9e0e. 66 tests, 0 failed.
⬜	micronaut-sql	7.2.x ✅	7.1.2	5.1.13	micronaut-projects/micronaut-sql#2100 → 5.2.0	✅	7.2.x, core c6158f9e0e. 446 tests, 68 failed: every DataSourcePoolMetadataSpec feature in jdbc-hikari (32), jdbc-tomcat, jdbc-dbcp and jdbc-ucp (12 each) gets 404 Not Found from the /metrics endpoint of released micronaut-micrometer 6.0.2. The same modules pass on core 5.1.13. This is a core regression: bisected to #12960 (d44e268). Update: core #13111 merged into 5.2.x (6d53fc7); the jdbc-hikari/-tomcat/-dbcp/-ucp pool metadata specs pass (47 tests, 0 failed) against core 5.2.x head 6d53fc7. Needs a core 5.2.1 release.
✅	micronaut-test	5.2.x ✅	5.1.1	5.2.0	micronaut-projects/micronaut-test#1517 → 5.2.0 (merged)	✅	5.1.x, core c6158f9e0e. 261 tests, 0 failed.
⬜	micronaut-test-resources	4.3.x	4.2.0	5.1.11	micronaut-projects/micronaut-test-resources#1214 → 5.2.0	⚠️	4.2.x. 398 tests, 12 failed. One is caused by core 5.2: TestResourcesClientTest "reasonable error message" gets "Internal Server Error" instead of the server's message, because core 05421f2 sets micronaut.server.error-response-include-message to never. This also hides test resources service errors from users; a module-side fix task has been spawned. The other 11 are local environment problems: 8 Oracle XE and MongoDB container start timeouts, 2 IntellijIdeaDatasourceExporterStandaloneProjectTest nested builds that cannot see the local core snapshot, and 1 macOS BindException in the H2 loopback test. Fix PR: micronaut-projects/micronaut-test-resources#1212.
✅	micronaut-toml	3.2.x ✅	3.1.0	5.2.0	micronaut-projects/micronaut-toml#371 → 5.2.0 (merged)	✅	3.1.x, core c6158f9e0e. 1152 tests, 0 failed.
⬜	micronaut-tracing	8.3.x ✅	8.2.0	5.1.7	micronaut-projects/micronaut-tracing#936 → 5.2.0	✅	8.3.x, core c6158f9e0e. 185 tests, 0 failed. :micronaut-tracing-bom:checkBom fails on the third-party opentelemetry-instrumentation-bom 2.30.0 (it declares opentelemetry-semconv from another group and imports another BOM). Not core related; suppress it in micronautBom or align OpenTelemetry.
⬜	micronaut-validation	5.2.x ✅	5.1.0	5.1.11	micronaut-projects/micronaut-validation#684 → 5.2.0	✅	5.2.x, core c6158f9e0e. 932 tests, 33 failed. 32 are Jakarta Validation TCK failures (constraint inheritance, group sequence inheritance, cross-parameter and generic validator resolution, property paths, ConstraintValidatorContext); the same TCK passes 384/384 on core 5.1.11, so this is a core regression, bisected to #12977 (2c9161c, add the micronaut-reflection module). Fixed by #13114: the TCK passes 384/384 on 5.2.x + #13109/#13111/#13114. The other is ValidatorSpec "@introspected is required to validate the bean", a known 5.2 behaviour change (500/500 on 5.1.11). Update: core #13114 merged into 5.2.x (9089b06); the Jakarta Validation TCK passes 384/384 against core 5.2.x head fc92af4. Needs a core 5.2.1 release.
✅	micronaut-views	6.3.x ✅	6.2.0	5.2.0	micronaut-projects/micronaut-views#1190 → 5.2.0 (merged)	⚠️	6.3.x, core c6158f9e0e. 587 tests, 2 failed. FreemarkerViewRendererSpec expects "Internal Server Error: View [bogus] does not exist", which core 05421f2 now hides by default (micronaut.server.error-response-include-message=never), so the test needs updating. TurboFrameSpec "/frame/disabled" hit a connection reset under load; it is flaky and passes 26/26 on 3 reruns. Baseline on core 5.1.7: views-freemarker 13/13 and views-turbo 99/99.
