A DESCRIPTION OF THE PROBLEM :
Running with the -Djava.awt.headless=true, I try to call JComponent.setBounds(), the headless exception occurs during JComponent.paint().

I have tested with jdk1.4.1_05 and it works fine, but version 1.4.2_06 and 1.5.0 both throw the HeadlessException.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. javac Headless.java
2. java -Djava.awt.headless=true Headless


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Paint worked ... ok

ACTUAL -
java.awt.HeadlessException
        at sun.java2d.HeadlessGraphicsEnvironment.getDefaultScreenDevice(Headles
sGraphicsEnvironment.java:65)
        at javax.swing.RepaintManager.getVolatileOffscreenBuffer(RepaintManager.
java:583)
        at javax.swing.JComponent.paintDoubleBuffered(JComponent.java:4869)
        at javax.swing.JComponent.paint(JComponent.java:993)
        at Headless.main(Headless.java:27)


REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
import javax.swing.*;
import java.awt.*;
import java.awt.image.BufferedImage;

public class Headless {
    public static void main( String[] args ) {
        BufferedImage img;
        try {
            img = new BufferedImage(10, 10, BufferedImage.TYPE_INT_ARGB );

            Graphics2D graphics = img.createGraphics();

            graphics.setRenderingHint(
                RenderingHints.KEY_ANTIALIASING,
                RenderingHints.VALUE_ANTIALIAS_ON );
            graphics.setColor( Color.white );
            graphics.fillRect( 0, 0, 600, 400 );

            JComponent comp = new JPanel();

            comp.setBounds( 0, 0, 600, 400 );

            // Un-comment the following line to allow it work on jdk1.4.2
            // and jdk1.5.0
            //comp.setDoubleBuffered( false );
            comp.paint( graphics );
            System.out.println( "Paint worked ... ok" );
        }
        catch ( Exception e ) {
            e.printStackTrace();
            System.exit( 1 );
        }
        System.exit( 0 );
    }
}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
The only workaround I found is to not set -Djava.awt.headless=true and to use Xvfb.

Release Regression From : 1.4.1_05
The above release value was the last known release where this
bug was known to work. Since then there has been a regression.
