Reproduce upstream Gradle 9.5.0 daemon OOM seen in CI by enabling: - -XX:+HeapDumpOnOutOfMemoryError with HeapDumpPath under $GITHUB_WORKSPACE/gradle-diagnostics - -Xlog:gc*,gc+heap=info,gc+age=info verbose GC logging (rotated) On job failure, copy the daemon log directory and any hs_err_pid*.log into the diagnostics directory and upload the whole tree as the 'gradle-daemon-diagnostics' artifact (retained 7 days). Temporary; intended to be reverted once the OOM root cause is identified.

OOM stack (daemon log)The OOM is in the daemon JVM itself — not a test worker fork (tests are skipped via Heap dump analysis (Eclipse MAT 1.16.1)
Suspect 1 — 677 MB (21.4%): build-operation queue not draining
Owner thread stack (parked acquiring a worker lock while the queue grows): Suspect 2 — 488 MB (15.4%): Guava caches holding incremental-compile data
Per-class retention inside the caches (subset):
Suspect 3 — 685 MB:

Diagnosis
The dump points at two coupled regressions in Gradle 9.5.0:
compileJavabuild-operation graph is never released.
161CompileJavaBuildOperationReportingCompiler/IncrementalResultStoringCompiler/CurrentCompilationAccessinstances — one per task — remain reachable after their tasks finish, each pinning a GuavaLocalCacheofClassSetAnalysisData/ClassAnalysis/DependentsSet. Cumulative impact: ~840 MB ofClassSetAnalysisDataalone, and 685 MB ofBuildOperationStatechained to them.DefaultBuildOperationQueue/TrackedManagedExecutornot draining.
"Build operations Thread 4" is parked inDefaultWorkerLeaseService.acquireLockswhile the executor'sLinkedBlockingQueuekeeps accumulating runnables (677 MB ofLinkedBlockingQueue$Nodes). Combined with (1), every queued op pins anotherBuildOperationDescriptorchain.
Diagnostics artifact
The CI run for commit e484ca2d uploaded a gradle-daemon-diagnostics artifact (≈1.3 GB compressed, 5.4 GB heap dump) containing:
daemon.hprof— heap dump (5.4 GB)gc.log— verbose G1 GC log (rotated)daemon-logs/9.5.0/daemon-2478.out.log— Gradle daemon stdoutsystem-info.txt—df -h/free -m/uname -a
Available for 7 days at https://github.com/open-telemetry/opentelemetry-java-instrumentation/actions/runs/25136630109.
