This problem will only occur in 4.0.3. Here are the steps
which would cause this problem to occur:

1. Request a servlet which creates/accesses a session.
2. Compile the servlet which will cause the webapp to be
reloaded.
3. Request the servlet again after the reloading has
completed. A NullPointer exception will be thrown. If the
servlet is requested again the page is served without any
problems.
Problem conclusion
This problem was occuring because the webapp was losing the
reference to the session context on a webapp reload.  The
webcontainer code has been changed so that the webapp has
the valid reference to the sessioncontext.
