> This error only happened at my tests only one time, not sure on how to reproduce it. I was looking for a similar error from netty project and I've found this link:
> https://github.com/netty/netty/issues/4198
> From the discussion at this link, it seems that the guy who reports the issue said that he was using netty incorrectly (not sure exactly what he meant about that). I'm creating this ticket because it's possible to get something similar from Artemis -  by using netty library unexpectedly.
