Re: leaking NioProcessors/NioSocketConnectors hanging in call to dispose

[Christoph John <ch...@macd.com>]

Sorry for coming back so late.
We were already closing the session in our implementation of the IoHandlerAdapter.exceptionCaught() 
but that did not seem to help.
I tried closing the session in our implementation of SSLFilter.exceptionCaught()as you suggested. 
Unfortunately I can still see the leaks. Will have to dig further.

Cheers,
Chris.
