ConcurrentModificationException when trying to close a job with an output data stream #1777

Closed arjansh closed 6 years ago

arjansh commented 6 years ago

When I have a job with an output data stream (but not just any job with an output data stream in it will do), and I try to close it, I can't close it and I get a ConcurrentModificationException like this:


Unexpected error!
