The java2demo main window dances off the center of the screen.
When you start java2demo, the main window (after the splash screen)
appears in the center of the screen and then dances to the right and down.
Not only is it wrong, but it looks bad because it creates a big flash.
This reproduces with XToolkit, but not with MToolkit.
This reproduces with the promoted build 1.5.0-beta-b30 on both
CDE/dtwm and Redhat9/Metacity.

To reproduce, run this:
jdkx2 -Dawt.toolkit=sun.awt.X11.XToolkit -r 1.5 java2demo
