                    CopyOnWriteArrayList/CopyOnWriteArraySet should throw NPE for removeAll(null)/retainAll(null) as noted in the specification in all cases.  A NPE is not thrown in the case where the CopyOnWriteArrayList/CopyOnWriteArraySet collection has no elements and then removeAll(null)/retainAll(null) is called.
