Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server V7.0.0 who make use of nested        *
*                  embeddables in their Jave Persistence       *
*                  API (JPA) entities.                         *
****************************************************************
* PROBLEM DESCRIPTION: Merging a JPA entity which contains a   *
*                      nested Embeddable causes an             *
*                      ArgumentException.                      *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
Take the following JPA Entity and Embeddables as an example:
@Entity
public class TestEntity {
@Id
private Long id;
@Embedded
private MyEmbeddedObject test;
..........
@Embeddable
public class MyEmbeddedObject {
@Embedded
private NestedEmbedded nestedEmbedded;
..........
@Embeddable
public class NestedEmbedded {
..........
In this case we have a nested Embeddable.  The
ArgumentException can occur when an attempt is made to update
or add a 'NestedEmbedded' to a detached 'TestEntity' instance,
and that 'TestEntity' instance is merged into the persistence
context.

Problem conclusion

With this fix, code has been added to properly handle the
merging of an entity with nested a Embeddable.

The fix for this APAR is currently targeted for inclusion in
Service Level (Fix Pack) 7.0.0.21 of WebSphere Application
Server version 7.0.0.
