--------------------------------------
NPEs are not always bad, they idetify real issues. You're getting this because most
likely the request has been recycled already.

Remy Maucherat resolved JBWEB-148.
----------------------------------
Fix Version/s: JBossWeb-3.0.0.GA
Resolution: Done
I have looked at the code, and other places in Request check for a null contexts. So I
have added checks as well in these places. However, this may end up hiding another issue.

----------------------------------
NPE's are bugs. this is equivalent to a core dump in C. thanks for adding the checks
maybe now it will expose the real problem.

Iyad Elian commented on JBWEB-148:
----------------------------------
also shouldn't you add a check at the beginning that the request has not been
recycled. It is common with a4j that you abandon requests. I am assuming this is
synchronized just by seeing a SynchronizationInterceptor in the stack.
