[JAVA2D] Bug in rendering text under JDK 6.0

[java2d]

I'm running the following code under JDK 6.0 on Vista. The second line of text 
is painted all garbled. The interesting thing here is that all three lines 
marked with the comments must be there:

1. Desktop hints must be installed
2. Another text must be painted under the default composite
3. A custom translucent SRC_OVER composite must be installed afterwards

[code]
public class TextRenderingBug extends JPanel {
        @Override
        protected void paintComponent(Graphics g) {
                Graphics2D graphics = (Graphics2D) g.create();

                // get the desktop hints and install them
                Toolkit toolkit = Toolkit.getDefaultToolkit();
                Map desktopHints = (Map) toolkit
                                .getDesktopProperty("awt.font.desktophints");
                if (desktopHints != null) {
                        // if this line is removed, everything is OK
                        graphics.addRenderingHints(desktopHints);
                }

                graphics.setColor(Color.black);

                // if this line is removed, everything is OK
                graphics.drawString("test", 10, 50);

                // if this line is removed, everything is OK
                graphics.setComposite(AlphaComposite.getInstance(
                                AlphaComposite.SRC_OVER, 0.6f));
                graphics.drawString("test", 10, 80);

                graphics.dispose();
        }

        public static void main(String[] args) throws Exception {
                SwingUtilities.invokeLater(new Runnable() {
                        public void run() {
                                JFrame fr = new JFrame("cool");
                                fr.setLayout(new BorderLayout());
                                fr.setSize(400, 300);
                                fr.add(new TextRenderingBug(), 
BorderLayout.CENTER);
                                fr.setLocationRelativeTo(null);
                                
fr.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                                fr.setVisible(true);
                        }
                });
        }
}
[/code]

Any insight on this particular scenario?

Thanks
Kirill
