The string width isn't computed correctly for antialiased bold text. Appears on Solaris & win32 : jdk1.2, jdk1.2.2, jdk1.3.

public class StringWidth extends Panel {

    public StringWidth() {
        setBackground(Color.white);

    public void paint(Graphics g) {
        Dimension d = getSize();

        g2.clearRect(0, 0, d.width, d.height);
        g2.setColor(Color.black);

        Font font = new Font("serif", Font.BOLD, 24);
        g2.setFont(font);

        String text = "Text should be right justified.";
        int xx = d.width-getFontMetrics(font).stringWidth(text);
        g2.drawString(text, xx, (int) (d.height*0.3));

        g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
        g2.drawString(text, xx, (int) (d.height*0.6));
