[8u40] Request for Approval: 6853696, 8038333, 8038982

[Ivan Gerasimov]

Hello!

Would you please approve backport of these three fixes?
The first one fixes an issue with ReferenceQueue.remove returning early, 
and the next two make the regression test created for the first fix more 
robust.
The fixes apply cleanly when applied in that order.

timeout has not expired
