<AWT Dev> Review request for JDK-8157476 -Wlogical-not-parentheses warnings in JRSUIConstantSync.m

[Dan Smith]

https://bugs.openjdk.java.net/browse/JDK-8157476

I noticed this code triggering a LOT of warnings when building under Xcode 7.3 in Mac OS X, and the fix is trivial.

(I'm guessing this native file belongs to AWT, but please redirect me if I'm wrong.)

If that looks okay, I'm happy to push this myself.  As noted in the bug comments, I think this is a legitimate bug fix, though -- so if somebody wants to write a test exposing the bug, you may just want to assign to yourself and take responsibility for pushing.

Thanks,
Dan
