Hello, Please review fix for JDK10:
bug: https://bugs.openjdk.java.net/browse/JDK-8189204 webrev: http://cr.openjdk.java.net/~ssadetsky/8189204/webrev.00/The fix eliminates possibility of NPEs in Component ::getLocationOnScreen(). Method Component ::getLocationOnScreen_NoTreeLock() does not consistently scan the component hierarchy because Component::getParent() may be overridden. Also there are may be issues caused by peer field concurrent updates.
