[9] Review request for 8167565: [macosx] Maximization of a dialog hides it

[Alexander Zvegintsev]

Hello,

please review the fix
http://cr.openjdk.java.net/~azvegint/jdk/9/8167565/00/

for the issue

https://bugs.openjdk.java.net/browse/JDK-8167565

We trying to zoom to a zero size window(standardFrame has zero size). 
standardFrame initialization happens on setMaximizedBounds call.
Dialog doesn't initialize it(Frames has setMaximizedBounds() call in 
Frame.addNotify).
I prefer to fix it in the native level, if you have other thoughts 
please share it.

Thanks,
Alexander.
