    True. I didn't wanna change the existing stack traces.
    This will require maintaining a global variable for whether the program was run in interactive
mode. The `DetachedProgramException` is a special case where we don't wanna clutter the stack
trace with flink's trace, instead just show the user program's stack trace.
    In other cases, this might not be the case.

This has been requested by users who want to submit a job, get the job id, and later query
its status.
