> 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.
