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.
