java antialiasing crashes gnome

English Applications

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:

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.
