[RFR] jdk9.0.4+12 + functionality

[Andrey Petushkov]

Dear Ed,

Thank you so much a try!
In fact there are two synchronization bugs found and fixed during updating to Java 10. So could I ask you to check out the jdk10 webrev I’ve sent last week. Hopefully some of the problems should go away. Unfortunately I did not yet run jcstress myself, shame on me…

The people participated are Fedor Burdun <fedor.burdun at azulsystems.com> and myself, Andrey Petushkov <andrey.petushkov at gmail.com>

Thanks again,
Andrey
