JDK-8174453	10	Tobias Hartmann	P2	Resolved	Fixed	b01

~~JDK-8087341~~ causes an anti-dependency on the volatile membar that results in a crash in the register allocator due to invalid instruction scheduling (see ~~JDK-8172850~~). Since we are very late in the JDK 9 release cycle, we should back out the change and redo the enhancement in JDK 10.
