JavaFX 2.1 and threads? -Using a JavaFX application?

I need a really easy way to play an mp3 file from a Java application. After some research, I found that the latest versions of Java 7 SE are packaged in JavaFX, so I decided to give it a try. This question is NOT about playing mp3 files, but about how to get JavaFX to work well.

So, in my first experiment with JavaFX, I used some code suggested in post to stackoverflow ( see here ) and created essentially the following test program:

import javafx.application.Application;
import javafx.stage.Stage;
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;

public class progtest extends Application
{

    /*---------------------------------------------------------*\
        FUNCTION:  main()
    \*---------------------------------------------------------*/
    public static void main(String args[])
    {

        launch(args);

    } /* END:  main() */

    /*---------------------------------------------------------*\
        FUNCTION:  start()
    \*---------------------------------------------------------*/
    @Override
    public void start(Stage stage)
    {

        Media medMsg 
            = 
            new Media(getClass().getResource("msg.mp3").toExternalForm());
        MediaPlayer medplMsg = new MediaPlayer(medMsg);
        medplMsg.play();

        System.out.println("Here.\n");

    } /* END:  start() */

}

(This is a little more complicated than my original test program: this version appeared after the offers from jewelsea made in response to an earlier question that I posted about how to run the program in general ( see here ).)
