<AWT Dev> JDK 9 b159 - sun.lwawt.macosx.CWrapper$NSWindow.isZoomed never returns

[dmitry markov]

Hi Reto,

I have no seen such hang before. Most likely this is a new issue.
Could you provide us with a test case, (i.e. reproducer), please? Once 
we have a reproducer, I will open a bug for this.

Thanks,
Dmitry
