Emmanuel Lecharny commented on DIRMINA-760:
-------------------------------------------
Ok I reused the chat server as a test, and had a client sending 100 000
messages, and killed the server in the middle of it. Here is the stackTrace I
get on the client :

Seems like it does what expected (at least in the version I'm currently working
on).
> Client fails to detect disconnection
> ------------------------------------
>
> Key: DIRMINA-760
> URL: https://issues.apache.org/jira/browse/DIRMINA-760
> Project: MINA
> Issue Type: Bug
> Components: Core
> Reporter: Omry Yadan
> Fix For: 2.0.8
>
>
> Tested against revision 901694 (which is a bit after 2.0.0-RC1)
> My client need to maintain an open connection to the server.
> If I kill the server right before calling session.write(), the client does
> not detect that the server is gone.
> there is no exceptionCaught event, and messageSent is actually called (which
> suggests successful delivery).
