PreCommit Java failed three times for different tests:

1. https://github.com/apache/beam/runs/20747937439
   1. testMetrics (org.apache.beam.runners.fnexecution.control.RemoteExecutionTest) failed
2. https://github.com/apache/beam/runs/20751137615
   1. testMultipleClientsFailingIsHandledGracefullyByServer (org.apache.beam.runners.fnexecution.logging.GrpcLoggingServiceTest) failed
3. https://github.com/apache/beam/runs/20754788594
   1. testSplit (org.apache.beam.runners.fnexecution.control.RemoteExecutionTest) failed
   2. testMultipleClientsFailingIsHandledGracefullyByServer (org.apache.beam.runners.fnexecution.logging.GrpcLoggingServiceTest) failed

I could not reproduce testMultipleClientsFailingIsHandledGracefullyByServer fail locally. tests passed multiple times (set test { outputs.upToDateWhen {false} })

This is a known flaky test: #30056 without this change it is also flaky. Most likely timing issues on GHA runner. Mark as ready for review.
