Description
When a Frame is in full screen mode all modal dialogs open behind that frame. The dialogs do receive input focus but are painted behind the frame window.
This happens on Linux Mint 14 only and is reproducible with Oracle JDK 1.7 update 10 and also with OpenJDK 1.7

To reproduce run the code below. Then tick the checkbox to switch to full screen mode and press the button to open modal dialog. The dialog will open behind the frame window.

import java.awt.GraphicsConfiguration;
import java.awt.GraphicsDevice;
import javax.swing.JDialog;
