http://wiki.apache.org/db-derby/NetworkServerSessionManagement mentions
bugs related to Network Sever Session management.
I was sure if DERBY-1020 belonged on this list or not. It is related
related to the proper handling of exceptions when an exception occurs
closing the session especially after the database has been shutdown.
There may be some synchronization impact as well because the exceptions
that occur when the database is intentionally shutdown are treated as
unexpected exceptions and it will not go through the normal session
shutdown codepath.
