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