Users on Linux have reported they get the following error while running DbVisualizer:

java.lang.IllegalArgumentException: Window must not be zero.
   at java.desktop/sun.awt.X11.XAtom.checkWindow(
   at java.desktop/sun.awt.X11.XAtom.getAtomData(

The problem is related having multiple screens and the root cause seem to be a bug in Java (JDK-8204646).

Some users have reported that using the following alias for running DbVisualizer has helped

alias dv='nohup dbvis & sleep 10 ; exit'
