I looked at the documentation for weak references again, and you are
right, there is no bug  in your code, all weak references to the
object are cleared before it is finalized.  Thus I am not sure that
removing it explicitly is such a good idea, a comment to explain that
it is not needed may be better.  My java/proxyFinalize2 branch is
useless for now.
