Guillaume Nodet commented on SSHD-228:
--------------------------------------
This is a configuration problem.
The key exception is "Unable to negociate key exchange for item 2 " which means
that there's no cipher algorithm matching both sides.
> java.lang.IllegalStateException: Session is closed issue for the two
> different j2ee application trying to do ssh in websphere Application Server
> cluster environment.
