See the Strange error by Tomcat thread for more info on this, but your
npe is happening a few lines after the error associated with Tomcat.
You are getting a npe when the user data is being stored to the database
as the session times out, it is likely to be harmless. Have you altered
o.a.t.util.map.TurbineMapBuilder? Other than that I would suggest
adding debugging statements to BasePeer where the npe is happening and
getting info such as is it the db map that is null or the table map and
what table name is being used to look for the map. Let us know if you
delve deeper.
