--------------------------------------------

Here is the tomcat issue:  http://issues.apache.org/bugzilla/show_bug.cgi?id=42934

If any of you jboss folks can use your tomcat contacts to get this looked at that would be nice. :)

> 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?
