Hello, Please review fix for JDK9:
bug: https://bugs.openjdk.java.net/browse/JDK-8132664 webrev: http://cr.openjdk.java.net/~ssadetsky/8132664/webrev.00/DoDragDrop() is blocking, so upon drag operation is triggered the toolkit thread is blocked and the WM_AWT_WAIT cannot be processed which in its turn blocks the AWT robot. The solution is to escape AWT robot waiting in syncNativeQueue() if drag operation is in progress.
