public class UnwrappedWeakReference<T>
extends WeakReference<T>

Smarter WeakReference that "unwraps" the referenced object in a few methods such as "equals()" which let a WeakReference be used in many other types of collections and lists and have them still work correctly. For exmaple, CopyOnWriteArrayList can be directly used with a UnwrappedWeakReference and have methods like "addIfAbsent" actually work correctly.
