    Description

      Currently, when a the method "SplitEnumeratorContext.runInCoordinatorThread()" throws an exception, the effect is a process kill of the JobManager process.

      The chain how the process kill happens is:

      • An exception bubbling up in the executor, killing the executor thread
      • The executor starts a replacement thread, which is forbidden by the thread factory (as a safety net) and causes a process kill.

      We should prevent such exceptions from bubbling up in the coordinator executor.
