>             Project: MINA
>          Issue Type: Bug
>    Affects Versions: 2.0.16
>            Reporter: Christoph John
>            Priority: Major
>         Attachments: mina-dispose-hang.txt, mina-test-patch.txt

> Follow-up to mailing list discussion.
> I was now able to reproduce the problem with a MINA test. Or let's say I did 
> the brute-force approach by re-running one test in an endless loop.
> I have attached a patch of the test (against 
> [https://github.com/apache/mina/tree/2.0]) and a stack trace. After a few 
> loops the test is stuck. You can see a lot of threads hanging in dispose() 
> and the test is stuck when it tries to dispose the acceptor.
>  
> What is a little strange is that the javadoc says that 
> connector.dispose(TRUE) should not be called from an IoFutureListener, but in 
> the test it is done anyway. However, changing the parameter to FALSE does not 
> help either.
>  
>  Is there anything that can be done to prevent this hang?
