    1.33 - * Weak reference objects, which do not prevent their referents from being
    1.34 - * made finalizable, finalized, and then reclaimed.  Weak references are most
    1.35 - * often used to implement canonicalizing mappings.
    1.36 - *
    1.37 - * <p> Suppose that the garbage collector determines at a certain point in time
    1.38 - * that an object is <a href="package-summary.html#reachability">weakly
    1.39 - * reachable</a>.  At that time it will atomically clear all weak references to
    1.40 - * that object and all weak references to any other weakly-reachable objects
    1.41 - * from which that object is reachable through a chain of strong and soft
    1.42 - * references.  At the same time it will declare all of the formerly
    1.43 - * weakly-reachable objects to be finalizable.  At the same time or at some
    1.44 - * later time it will enqueue those newly-cleared weak references that are
    1.45 - * registered with reference queues.
