I had same problem and I found solution after two hours of searching and 5 minutes of carefully reading of JavaDoc.:)

Notifications send by notifyPreloader() method can be handled only by Preloader.handleApplicationNotification() method and it doesn't matter which type of notification are you sending.

So change you code like this:

   @Override
   public void handleApplicationNotification(PreloaderNotification arg0) {
          if (arg0 instanceof ProgressNotification) {
             ProgressNotification pn= (ProgressNotification) arg0;
             bar.setProgress(pn.getProgress());
             System.out.println("Progress " + bar.getProgress());
          }
    }
}
