### Bug description The pre-merge workflow is failing due to a flaky Java SDK test in PR #3515. Failing run/job: Run: https://github.com/apache/iggy/actions/runs/28737059115?pr=3515 Job: https://github.com/apache/iggy/actions/runs/28737059115/job/85213039410?pr=3515 Observed failure in logs: AsyncConsumerGroupsTest > shouldHandleConcurrentJoinAndLeaveOperations() FAILED java.util.concurrent.ExecutionException at AsyncConsumerGroupsTest.java:345 Caused by: org.apache.iggy.exception.IggyResourceNotFoundException at IggyServerException.java:169 Test summary: 1032 tests completed, 1 failed, 4 skipped Why this matters This failure blocks pre-merge CI and appears to be a race/flakiness issue in concurrent join/leave consumer group operations in Java SDK tests. Expected behavior shouldHandleConcurrentJoinAndLeaveOperations should pass deterministically under CI load and timing variance. Actual behavior During concurrent operations, the test intermittently sees IggyResourceNotFoundException, causing the test task to fail. Proposed fix Harden the test against transient race windows / eventual consistency: Add synchronization to ensure all concurrent tasks are started and completed before final assertions. Wrap transient IggyResourceNotFoundException in bounded retry during concurrent phase. Replace immediate final assertions with short bounded polling until state stabilizes. Keep strict failure for non-transient exceptions. Acceptance criteria Java SDK test suite passes consistently in CI for this scenario. AsyncConsumerGroupsTest.shouldHandleConcurrentJoinAndLeaveOperations no longer flakes. No regression in consumer group join/leave behavior. Pre-merge workflow passes for affected PRs. Scope foreign/java/java-sdk tests (primarily AsyncConsumerGroupsTest) If needed, evaluate server-side consistency assumptions only if test hardening is insufficient. ### Affected area / component CI / build / tooling ### Deployment None ### Versions _No response_ ### Hardware / environment _No response_ ### Sample code _No response_ ### Logs > Task :iggy:test AsyncConsumerGroupsTest > shouldHandleConcurrentJoinAndLeaveOperations() FAILED java.util.concurrent.ExecutionException at AsyncConsumerGroupsTest.java:345 Caused by: org.apache.iggy.exception.IggyResourceNotFoundException at IggyServerException.java:169 ### Iggy server config _No response_ ### Reproduction Its a flaky failure.
