[PR] [BP-2.2][FLINK-38908][flink-runtime][test] Fix flaky ExecutionPartitionLifecycleTest [flink]
MartijnVisser opened a new pull request, #29319:
URL: https://github.com/apache/flink/pull/29319
Backport of https://github.com/apache/flink/pull/27406 (76fbab4f20c), which went to master and release-2.3 but not to this branch.
The test uses `forMainThread()` next to a separate I/O executor. The main-thread step of `Execution.deploy()` then runs on the I/O thread and fails its thread assertion, so the partitions are released too early. The fix waits for the deployment descriptor and runs the scheduler calls on a dedicated main-thread executor.
Last occurrence on this branch in the nightly of 2026-09-25, `test_cron_jdk21 core`: https://dev.azure.com/apache-flink/98463496-1af2-4620-8eab-a2ecc1a2e6fe/_build/results?buildId=79415&view=logs&j=d06b80b4-9e88-5d40-12a2-18072cf60528
Verified locally on JDK 17 under CPU load, with assertions enabled as in surefire. `ExecutionPartitionLifecycleTest` fails in 14 of 500 runs on the base commit and in 0 of 500 with this change. 13 of the 14 failures show the CI error. `spotless:check` and `checkstyle:check` pass.
