Mark Payne commented on NIFI-437:
---------------------------------
Brian - is the result reproducible or did it just happen once? My guess,
looking at the code, is that in the unit test it couldn't bind to the port that
it wanted to bind to, and as a result it called "stop", which threw this
Exception. So basically, I think this error is masking a different problem. I
attached a patch that will cause is to not call "close" if the server socket is
already closed. Can you try applying this patch and see if the unit test passes
- or if it now provides a different error?
