<AWT Dev> [8] Request for review: 7124339 [macosx] setIconImage is not endlessly tolerant to the broken image-arguments

[Sergey Bylokhov]

Hello,
Please review the fix for jdk 8.
After the fix of 6436455 we skip window's incorrect icon on all platforms.
In this fix we do the same for OSX. See additional info in the bug 
description
Input validation was removed, because it is done in the createFromImages()
