I suggest to file a separate issue to follow up. I don't think that clause can be dropped, because of explicit clearing (by clear() or enqueue()) rather than by the GC. If the reference was constructed with a null referent, ref.refersTo(null) cannot tell whether ref.clear() has been called. ------------- PR: https://git.openjdk.java.net/jdk/pull/498
