Please, review:

bug: https://jbs.oracle.com/bugs/browse/JDK-7147075
webrev: http://cr.openjdk.java.net/~ant/JDK-7147075/webrev.0

I'm copying comments from jbs:

It's a regression of 6613426 (integrated in jdk7 b27). 6613426 is a 
workaround for a Metacity issue [1].

Some WMs (which are reported to fail: e16, IceWM, CygwinX) don't 
strictly follow "Global Active" focus model specification [2], which 
assumes that a WM doesn't set focus to a window, but only notifies it 
with WM_TAKE_FOCUS client message (for example, when the window is 
clicked). But the focus log (sun.awt.X11.level=ALL) shows that the frame 
is natively focused right after it receives WM_TAKE_FOCUS which prevents 
the frame from normal activation (due to the fix for 6613426).

Suggested fix: http://cr.openjdk.java.net/~ant/JDK-7147075/webrev.0

It narrows down the scope of 6613426 to Metacity WM only.
