PROBLEM SUMMARY

USERS AFFECTED:
 All users of IBM WebSphere Application
Server

PROBLEM DESCRIPTION:
NullPointerException in webbeans
ContextFactory during shutdown

RECOMMENDATION:
None

While shuting down WebSphere Application Server a
NullPointerException may occur in the
org.apache.webbeans.context.ContextFactory due to a race
condition with a request running concurently on one thread is
being terminated while the WebSphere Application Server
shutdown code runs on another thread.

PROBLEM CONCLUSION:                                             
The code has been updated to check if the Context has already   
been destroyed before attempting to deactive a context.
