<AWT Dev> [9] Review Request for JDK-8004148: NPE in sun.awt.SunToolkit.getWindowDeactivationTime

[Anton V. Tarasov]

Hello,

Please, review the fix.

https://bugs.openjdk.java.net/browse/JDK-8004148
http://cr.openjdk.java.net/~ant/JDK-8004148/webrev.0

There's no a test case for the original issue. However, there's another test case which reproduces 
NPE with the same stack trace. The problem was fixed in jdk8 in JDK-8001633.

However, I suggest to do a sanity check for null. I check for null AppContext which covers the case 
for null Window as well.

Thanks,
Anton.
