The session ID created in clustered instances of earlier JBoss EAP versions contained a full source in a deployed bean's metadata (used to create a session ID). This was causing beans deployed across different nodes in the cluster to be recreated if a session ID was reused when accessing a different node. A NullPointerException could also been seen in the later node's log. New code has been introduced that obtains a relative path, rather than an absolute path. Beans are no longer recreated and the NPE no longer presents.
