Hello AWT team,
Could you please review the fix for bug:
bug: https://bugs.openjdk.java.net/browse/JDK-8046391
webrev: http://cr.openjdk.java.net/~aivanov/8046391/jdk9/webrev.01/
Description:
The fix for JDK-8039383 "NPE when changing Windows Theme" caused a
regression where JFileChooser hung. The root cause is the deadlock
between Windows Toolkit thread and AWT Event Queue which is caused by
the fact that ThemeReader.flush() is called on the toolkit thread.
The fix:
Modify ThemeReader so that flush() does not do the real work but marks
the current state as invalid. The old theme data are removed when
getTheme() is called which is done only from an Event Dispatch thread.
Regards,
Alexey.
