Believed caused by JMS client setting non-zero timeout on a session which has some unacknowledged messages held in it, then the broker shutting down.

In the normal case the session would be closed when detached and this would be prevented from happening (see bug 610493). The case above is where the connection has already closed but this does not close the session.
