ISBN 0 201 48552 4 discusses phantom references - p 698.

I think they're supposed to be a generalization of finalizable
objects (with wrinkles - see soft/weak references also) - rather
than just a finalize() method of a finalizable object, _any_
object can be notified when some object of interest becomes
garbage.
