JavaFX 8 JVM remains after exit

I have created a JavaFX application, and noticed that after I close the main stage, the following happens:

I do not create any threads (explicitly not, at least). The threads that are running at this point are (from the debug console):

Which of these threads can stop the JVM from closing? I would think that all of these should be daemon threads...

Here is my Application code:

public class MainApp extends Application {

@Override
public void start(Stage stage) throws Exception {       
    final FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("/fxml/Main.fxml"));
    Parent root = fxmlLoader.load();

    Scene scene = new Scene(root);
    scene.getStylesheets().add("/styles/Styles.css");

    //... Scene/stage setup here
    stage.show();
}

@Override
public void stop() throws Exception {
    super.stop();
}

public static void main(String[] args) {
    launch(args);
}
}

Adding a System.exit(0); on the end of the stop() method fixes this, but I'm not sure if this is the best solution to the problem... Any ideas?

Thx in advance

You say you are using a HSQLDB, you don't show the code where you initialize it. In your stop() method, close that connection.
