>          Issue Type: Bug
>          Components: Runtime / Checkpointing
>    Affects Versions: 1.12.0, 1.11.3

> Introduced in FLINK-8871, aborted RPC notifications are done asynchonously:
>  
> {code}
> 	private void sendAbortedMessages(long checkpointId, long timeStamp) {
> 		// send notification of aborted checkpoints asynchronously.
> 		executor.execute(() -> {
> 			// send the "abort checkpoint" messages to necessary vertices.
>                         // ..
> 		});
> 	}
> {code}
> However, the executor that eventually executes this request is created as follows
> {code}
> 		final ScheduledExecutorService futureExecutor = Executors.newScheduledThreadPool(
> 				Hardware.getNumberCPUCores(),
> 				new ExecutorThreadFactory("jobmanager-future"));
> {code}
> ExecutorThreadFactory uses UncaughtExceptionHandler that exits JVM on error.
