<AWT Dev> KDE Task bar is always on top of fullscreen Java applications

[gouessej at orange.fr]

Hi!

I think I have found a fix for this bug. On GNOME and on KDE the atoms remain unchanged according to xprops but the X client message is sent, that is why I call XChangeProperty. On the other hand, only a window on top of the stack can become fullscreen, that is why I use _NET_WM_STATE_ABOVE. I fear that building OpenJDK requires a lot of time. Could someone with a ready environment make a build for me with this fix? My "patch" is in the bug report here:

Best regards
