Ooops... Seems like I just looked at the code snippet.

Could you post the complete code so that we can tets it ?

Thanks !



OK.  It's tied up with some proprietary code right now, but I'll try 
to trim it down to an isolated test case and post it.


Thanks,

Try this:

Hmmm .... dunno.  Just wasted a lot of time trying to debug through 
this, and I really have no idea.  I wound up just having the unit test 
manually issue a session.getCloseFuture().setClosed(); in order to 
trigger the close listener notification.


BTW, there also appears to be a bug when calling DummySession.close(false):
