> 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.
