Error description

When deserializing the object data placed in DistributedMap, the
following error may occur, if the failing class is present in
the classpath for ExtClassloader:

Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server using dynamic caching replication    *
*                  or disk offload.                            *
****************************************************************
* PROBLEM DESCRIPTION: A NoClassDefFoundError exception can    *
*                      occur when deserializing a cache        *
*                      entry that has been replicated or       *
*                      offloaded to disk.                      *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
Cache entries are serialized prior to being replicated or
offloaded to disk.  The cache entry then needs to
be deserialized when it is retrieved from disk or received from
replication. If a class can not be found the class will be
searched again after switching classloaders.

Problem conclusion

NoClassDefFoundError has been added to the list of exceptions
caught during deserialization.

The fix for this APAR is currently targeted for inclusion in
fix packs 6.0.2.43, 6.1.0.33 and 7.0.0.13.  Please refer to the
