The swing-UI of Java-programs doesn't work perfectly together with the awesome-wm. awesome is a window-manager for UNIX, that automatically resizes program-windows, and the Swing-UI doesn't recognize these resizes correctly. I don't care if awesome or Java is guilty, what I wanna know if I can change my Java-programs in a way, that they will work with awesome. So that users of my programs get the correct experience, even when they use exotic window-managers.
From the man page of awesome:
BUGS
Of course there´s no bug in awesome. But there may be unexpected behaviours.
Java applications which use the XToolkit/XAWT backend may draw grey windows only. The XToolkit/XAWT backend breaks ICCCM-compliance
in recent JDK 1.5 and early JDK 1.6 versions, because it assumes a reparenting window manager. As a workaround you can use JDK 1.4
(which doesn´t contain the XToolkit/XAWT backend) or you can set the following environment variable (to use the older Motif backend
instead): AWT_TOOLKIT=MToolkit
