    Default java antialiasing crashes gnome

    I'm working with java and trying to do some anti-aliasing drawing. I used some code that I found in a book, and it causes my computer to crash. (GNOME becomes unresponsive, fragments of the screen get shifted around, windows become invisible, etc) If I hit ctrl+alt+backspace then it gets me out and I can log back in, but that's my only option at that point.

    I'm running the following code in eclipse:

    Code:
    import java.awt.*;
    
    public class GraphicsTest extends ApplicationFrame {
    
    	public void paint(Graphics g) {
    		Graphics2D g2 = (Graphics2D) g;
    		
    		Shape shapeOne = new Ellipse2D.Double(40, 20 , 80, 80);
    		Shape shapeTwo = new Rectangle2D.Double(60, 40 , 80, 80);
    		
    		setBackground(Color.WHITE);
    		setLayout(new BorderLayout());
    		
    		g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
    		
    		g2.draw(shapeOne);
    		g2.draw(shapeTwo);
    	}
    	
    	public static void main(String[] args) {
    		GraphicsTest g = new GraphicsTest();
    		g.setTitle("Graphics");
    		g.setSize(300, 150);
    		g.center();
    		g.setVisible(true);
    	}
    
    }
    if i comment out:
    g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
    then everything runs fine, so obviously it's a problem with the antialiasing.

    I'm not even sure where I should begin to start trying to fix this.

    EDIT: BTW, it works fine in KDE3, so it has to be a gnome problem.
