Hi Friends,

Use of Reference Queue with soft reference and weak reference is optional,
but each phantom reference you must be associated with ReferenceQueue, WHY?

Okay, let's assume that there was an option to declare a phantom reference without a ReferenceQueue -- how do you propose that it be used?
