ConcurrentHashMap.CollectionView is the root of a small class hierarchy with subclasses KeySetView, ValuesView, and EntrySetView. All are serializable, and none are publicly subclassable. CollectionView could be made a sealed class that permits those specific subclasses, and KeySetView in turn could be made final. (ValuesView and EntrySetView are already final.)
