Gavin King commented on JBSEAM-1681:
------------------------------------

Surely we should regard this as a bug in Tomcat?

> I'm running Seam in tomcat 5.5.23.  When I shutdown I get an NPE.  It appears that contextDestroyed is being called before tomcat does the session passivation.  Any opinions on the best way to deal with this?  It's obviously fairly harmless but the message is semi annoying?
