Where has brushed metal effect gone in final release of 1.7.0_10 of jdk?

[Paul Taylor]

Hi, I was building my application against 1.7.0_10-ea 23.6-b03 and using 
AppBundler with

<option value="-Dapple.laf.useScreenMenuBar=true"/>

my application had a brushed metal effect

Now Ive just built with the application with the final release of 
1.7.0_10 (build 1.7.0_10-b18) and my app no longer has brushed metal effect.

What has happened to it ?
Do I need to use a different option to enable it ?

thanks Paul
