 * does nothing.//ww w .ja  v  a  2 s. c  o m
 * 
 * This method should be called when the application exits. But it is
 * not a requirement. When you don't do this then the port number will
 * stay in the preferences so on next start of the application this port
 * number must be validated. So by calling this method on application exit
 * you just save the time for this port validation.
 * 
 * @param mainClass
 *            The main class of the application. Must not be null.
 *            This is used as the user node key for the preferences.
