Transaction rollback does not restore contents of collection of cached collections
----------------------------------------------------------------------------------

                 Key: JBCACHE-763
                 URL: http://jira.jboss.com/jira/browse/JBCACHE-763
             Project: JBoss Cache
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: PojoCache
            Reporter: Nitzan Niv
         Assigned To: Manik Surtani


In PojoCache, transaction rollback does not restore (by completely undoing modifications) the contents of a cached collection when the updated element is in itself a cached collection.

1. create 2 "data elements" in the cache which are Map instances.
2. create a "data elements container" in the cache which is a Map instance.
3. initalize the container with one data element.
4. in a transaction, replace the initial data element in the container with the other data element, and then rollback the transaction.

After the rollback the element in the container is neither the new data element nor the old data element.

It looks like the aopInstance reference in the internal CachedMapInterceptor is not restored by the rollback and contains null after it.
