/**
 * Installs the handler which determines if the application should quit. The

 * proceed with the quit. Setting the handler to {@code null} causes
 * all quit requests to directly perform the default {@link QuitStrategy}.
 *
 * @param quitHandler the handler that is called when the application is
 * asked to quit
 *
 * @throws SecurityException if a security manager exists and it
 * will not allow the caller to invoke {@code System.exit} or it denies the
 * {@code RuntimePermission("canProcessApplicationEvents")} permission
 * @throws UnsupportedOperationException if the current platform
 * does not support the {@link Desktop.Action#APP_QUIT_HANDLER} action
