Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server                                      *
****************************************************************
* PROBLEM DESCRIPTION: A MetaDataException occurs declaring    *
*                      that a custom mapping strategy cannot   *
*                      be instantiated by OpenJPA.             *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The ValueHandlers for custom mappings (such as ClassStrategy,
DiscriminatorStrategy, etc) tries to load the class using the
OSGi ClassLoader, and not the application's ClassLoader.
Because custom classes do not reside in that level of the
ClassLoader hierarchy, the lookup fails and is reported as a
MetaDataException.

Problem conclusion

The strategy to locate a Class type requested by the
MappingRepository has been enhanced to leverage the configured
ClassResolver.

The fix for this APAR is currently targeted for inclusion in
fix packs 7.0.0.25, 8.0.0.4, and 8.5.0.1.  Please refer to the
