<AWT Dev> Window Decorations do not work on x86_64

Hi all,

I responded to Artem directly, but I'm going to post my response here 
for those that are interested.

I am using Gnome 2.18.3 running on Fedora 7.  Metacity is my window 
manager, and I have tried "metacity --replace" with no effects.  I am 
not running any composite extensions, or even a proprietary video driver 
(I use VESA and have an ATI video card).  The latest binary JDKs do not 
cause this issue, it is only seen with OpenJDK/IcedTea (although it has 
been fixed in IcedTea 1.2 released today).

I have also enclosed a screenshot of a simple awt app that appears 
correctly on 32-bit systems, but, as can be seen, is missing window 
decorations on our x86_64 machines.

Hope that helps.
