Metrics of space character in algorithmically emboldened font have changed in JDK 7.

The following test program shows different metrics between JDK 6 and JDK 7
Its extreme if you use the "all spaces" string.
Note run on Windows as its using a Windows font.

public class Gulim extends JComponent {

  public static void main(String args[]) {
    JFrame frame = new JFrame("Korean font test");
    frame.setBounds(100, 100, 600, 500);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.add(new Gulim());
   frame.setVisible(true);
}
