package de.schlichtherle.key.passwd.swing;

/**
 * Provides feedback by beeping using the default toolkit.
 * when prompting for a key to open an existing protected resource
 * for the first time.
 * 
 * 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).
