ok, I think, I understood the intention of `TaskExecutor#onFatalErrorAsync`
wrong - it is meant for outside `TaskExecutor` thread calls to run the error
handler inside the `TaskExecutor` thread...
I'll create a new approach
> MiniCluster can deadlock at shut down

> Key: FLINK-7279
> URL: https://issues.apache.org/jira/browse/FLINK-7279
> Project: Flink
> Issue Type: Bug
> Components: Tests
> Affects Versions: 1.4.0
> Reporter: Till Rohrmann
> Labels: flip-6
>
> The {{MiniCluster}} can deadlock in case if the fatal error handler is called
> while the {{MiniCluster}} shuts down. The reason is that the shut down
> happens under a lock which is required by the fatal error handler as well. If
> now the {{MiniCluster}} tries to shut down the underlying RPC service which
> waits for all actors to terminate, it will never complete because one actor
> is still waiting for the lock.
> One solution would be to ignore the fatal error handler calls if the
> {{MiniCluster}} is shutting down.
