exception, such as "The jobgraph is empty" message.

> JobSubmitHandler does not handle JobSubmissionExceptions
> --------------------------------------------------------

> Key: FLINK-8785
> URL: https://issues.apache.org/jira/browse/FLINK-8785
> Project: Flink
> Issue Type: Bug
> Components: Job-Submission, JobManager, REST
> Affects Versions: 1.5.0
> Reporter: Chesnay Schepler
> Assignee: buptljy
> Priority: Critical
> Labels: flip-6
>
> If the job submission, i.e. {{DispatcherGateway#submitJob}} fails with a
> {{JobSubmissionException}} the {{JobSubmissionHandler}} returns "Internal
> server error" instead of signaling the failed job submission.
> This can for example occur if the transmitted execution graph is faulty, as
> tested by the \{{JobSubmissionFailsITCase}}.
