/** <p>
 *    A map that is backed by a Java weak hash map, whose keys are maintained
 *    as weak references.
 *  </p>
 *  <p>
 *    Because keys are weak references, the garbage collector can collect
 *    them if they are not referred to elsewhere.
 *  </p>
 *  <p>
 *    Useful for implementing caches.
