PojoCache Collection sub-field when detached will revert back to the original reference
---------------------------------------------------------------------------------------

                 Key: JBCACHE-697
                 URL: http://jira.jboss.com/jira/browse/JBCACHE-697
             Project: JBoss Cache
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: PojoCache
            Reporter: Ben Wang
         Assigned To: Ben Wang
             Fix For: POJOCache


In PojoCache 1.4, when a Pojo has a Collection sub-object, it will dynamically replace the reference with a corresponding ClassProxy one such that we can intercept the Collection APIs. This is in attached state. When the POJO is detached, we would simply keep the ClassProxy reference but rather point the interceptor to the original reference. This works fine except when the POJO is meant for remoting as ClassProxy is not Serializable and not for direct manipulation.

The solution is when a POJO is detached, it will dynamically swap back the original reference and discard the ClassProxy. This way, it is semantically similar to a regular POJO as well. There will be no issue of Remoting, as an example.
