[9] Review Request: JDK-8036112: JColorChooser throws a NPE when applet with static reference is reloaded

[dmitry markov]

Hello,

Could you review the fix for jdk9, please?
bug: https://bugs.openjdk.java.net/browse/JDK-8036112
webrev: http://cr.openjdk.java.net/~dmarkov/8036112/jdk9/webrev.00/

Problem description: the EventQueue object stored in AppContext for 
static fields of an applet becomes null after the refresh of the web 
page. This may cause a NPE in swing/awt code.

Fix: The method SunToolkit.getSystEmeventQueueImplPP(AppContext 
appContext) should be modified. If the EventQueue from the passed 
AppContext is null, the method will retrieve the EventQueue from the 
default AppContext.

Thanks,
Dmitry
