<AWT Dev> Review request for CR-7179050 : [macosx] Make LWAWT be able to run on AppKit thread

[Sergey Bylokhov]

Hi, Petr.
Small comments from the quick view:

ThreadUtilities performOnMainThreadWaiting should not be called from the 
main thread with YES. I guess it should throw the same error as before 
the fix.
