Hello,

Please review fix for JDK9:

bug: https://bugs.openjdk.java.net/browse/JDK-8130769
webrev: http://cr.openjdk.java.net/~ssadetsky/8130769/webrev.00/

This is regression from JDK-7155957. Menu should be added to MenuBar 
collection before the adding it to MenuBar's peer otherwise it is not 
painted.
