Java's GraphicsDevice.setFullScreenWindow fails

[Hollis Waite]

When Guest Additions are installed on an Ubuntu guest VM running Unity, Java's GraphicsDevice.setFullScreenWindow(Window) fails to obscure the Unity panel.

import javax.swing.*;
import java.awt.*;

public class Test {
  public static void main(String[] args) {
    final JFrame f = new JFrame();
    f.setUndecorated(true);
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    f.pack();
    final GraphicsDevice device =
     GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice();
    System.out.println(device.isFullScreenSupported());
    System.out.println(device.getDefaultConfiguration().getBounds().getSize());
    device.setFullScreenWindow(f);
    f.setVisible(true);
  }
}
