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

[dmitry markov]

Hi Reto,

Thank you for the testcase. I was able to reproduce the problem using it.
I have opened JDK-8176490 
<https://bugs.openjdk.java.net/browse/JDK-8176490> for this issue. Will 
look into this.

Thanks,
Dmitry
