Please review fix for JDK9:

bug: https://bugs.openjdk.java.net/browse/JDK-8143295
webrev: http://cr.openjdk.java.net/~ssadetsky/8143295/webrev.00/

In the 8011616 window bounds that are sent from WM were propagated to 
the component for XWindow and its descendants. But in case of AWT 
components which are managed by a container layout, this may cause an 
issue because their bounds may be concurrently modified by the container 
layout in another thread.
For the components other than windows it is not necessary to propagate 
bounds sent by WM because those component bounds should be controlled by 
the container layout only. So the solution is to apply 8011616 fix on 
XWindowPeer level and restore the original logic of the ConfigureNotify 
event handler of the XWindow class.
