Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server with applications that use Contexts  *
*                  and Dependency Injection (CDI) managed      *

* PROBLEM DESCRIPTION: NullPointerException for CDI managed    *

* RECOMMENDATION:                                              *
****************************************************************
When an application contains a CDI managed bean with
either @EJB or @Resource injection, then the following
exception may occur:
java.lang.NullPointerException

Problem conclusion

In the failing scenario, the managed bean container is
incorrectly interpreting the CDI managed bean as an
instance of a bean with the javax.annotation.ManagedBean and
preventing the CDI managed bean from being created. The
managed bean container has been corrected and will now
properly identify and manage only beans with the
javax.annotation.ManagedBean annotation. The
NullPointerException will no longer occur.

The fix for this APAR is currently targeted for inclusion in
fix pack 9.0.0.1.  Please refer to the Recommended Updates
