****************************************************************
* USERS AFFECTED:  IBM WebSphere Application Server Full       *
*                  Profile versions 8.0 and 8.5.5 users of     *
*                  Contexts and Dependency Injection (CDI).    *
****************************************************************
* PROBLEM DESCRIPTION: CreationalContextImpl incorrectly       *
*                      synchronizes updates to an internal     *
*                      Map leading to problems in a            *

* RECOMMENDATION:                                              *
****************************************************************
The CDI implementation incorrectly synchronizes updates to an
internal Map, which might lead to a
java.util.ConcurrentModificationException. The exception might
look like the one below:
Caused by: java.util.ConcurrentModificationException
at
java.util.WeakHashMap$HashIterator.next(WeakHashMap.java:244)
at
org.apache.webbeans.context.creational.CreationalContextImpl.rem
oveAllDependents(CreationalContextImpl.java:368)

Problem conclusion

The CDI implementation was modified to correctly synchronize
its activity in CreationalContextImpl to avoid the
ConcurrentModificationException.

The fix for this APAR is currently targeted for inclusion in
fix packs 8.0.0.9 and 8.5.5.3.  Please refer to the
