A little unclear on how this NPE could have arisen. Possible root causes are that either a NULL object got inserted into the map used to track sessions or perhaps concurrent modification of the map (which seems unlikely if only one thread is access the client). Will change the collection used to track JobServerSessions from a HashMap to a Hashtable (which does not allow nulls and protects against concurrent modification).
