Priority:	Major
Reporter:	Damian Pelinko

We notice performance problems with method entrySet on IdentityMap. Method entrySet creates HashSet with all entries, problematic is put because of hash implementation in IBM JDK.
We made changes based on HHH-1612 issue and BatchFetchQueue.getCollectionBatch and AbstractFlushingEventListener.postFlush
