Steps:
1. run the following program.Use mouse to press "go"
   button. A modal dialog appears.
2. Press 'Enter' key on the Keyboard. A value '0' is typed
   on the MS-DOS prompt window.
3. Press the 'go' button again, the dialog appears again.
   This time use the 'Tab' key on the keyboard to move the focus
   to next button, and press 'Enter' key.
4. A same value of '0' is printed on the MS-DOS prompt window again.
Conclusion:
The KeyEvent is not handled properly on JOptionPane.
