Browse source 
* java/lang/ref/natReference.cc (add_to_hash): Look at `copy', not
	`referent'.
	(finalize_referred_to_object): Don't modify `referent' or `copy'
	fields.
	(add_to_hash): Correctly set `n->next' when updating list.
	* java/lang/ref/Reference.java (enqueue): Return false if already
	enqueued.
