Hi Zhuoren,
I don't actually know what behaviour to expect from the Unsafe atomics
in this test-case but perhaps you could re-cap the original problem
(addressed in JDK-8246051) since it seems to raise some questions. Did
you have an example (real code) where this behaviour is essential?
Best regards,
Patric Hedlin
