Keyboard problems with joptionpane.ShowConfirm

Question

hello,
I am using show confirm dialog and there is a yes and no button with it.
I want the software to exit when the user clicks yes button.
the code works fine when the user uses mouse. but when I use the enter key on yes or no button, the application exits in both the cases.
further more if I perform the same action with the space bar on the keyboard it still works fine and when I hit space bar on the no button the application stays. but with enter key the application doesn't seam to take the right yes/ no value in the integer.
what's the problem
and how do I correct it.
thanks
Krishnakant.

import javax.swing.*;
class Testing
   public Testing()
      try{UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");}
      catch(Exception e){e.printStackTrace();}
      int btn = JOptionPane.showConfirmDialog(null,"tab to a button, then press [ENTER]",
                                                         "",JOptionPane.YES_NO_OPTION,-1);
      String selection = "Escape (or 'x') selected";
      if(btn == 0) selection = "Selection = 'Yes'";
      else if(btn == 1)  selection = "Selection = 'No'";
      JOptionPane.showMessageDialog(null,selection);
      System.exit(0);
  public static void main(String[] args){new Testing();}
}
