20  * Provides feedback by beeping using the default toolkit and disabling the
21  * default button in the root pane for three seconds
22  * when prompting for a key to create or overwrite a protected resource
23  * and the last input was invalid.
24  * <p>
25  * Note that the root pane is normally the root pane of an enclosing
26  * JOptionPane which has the OK button set as its default button.
27  * This is to inhibit the use of a GUI robot for exhaustive password searching.
28  * <p>
29  * If you would like to play a nice sound for feedback, you need to override
30  * the {@link #startSound} method.
31  * <p>
32  * <b>Warning:</b> Playing a <code>java.applet.AudioClip</code> on J2SE
33  * 1.4.2_12 causes a client application not to terminate until System.exit(0)
34  * is called explicitly - hence this feature is currently not implemented in
35  * this class!
36  * This issue is fixed in JSE 1.5.0_07 (and probably earlier versions).
