JavaFX application on Mac OS

Question

I've written app on JavaFX and it's starting successfully on Linux and Windows, but not on mac os. It's showing in processes and there is no exceptions or errors, but GUI not showing. What special is needed to start such app on mac?

I also tried simple hello world application:

public class TestApp extends Application {
  @Override
    public void start(Stage primaryStage) {
        primaryStage.setTitle("Hello World!");
        Button btn = new Button();
        btn.setText("Say 'Hello World'");
        btn.setOnAction(new EventHandler<ActionEvent>() {

            @Override
            public void handle(ActionEvent event) {
                System.out.println("Hello World!");
            }
        });

        StackPane root = new StackPane();
        root.getChildren().add(btn);
        primaryStage.setFullScreen(true);
        primaryStage.setScene(new Scene(root, 300, 250));
        primaryStage.show();
    }


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

}

without no luck ( the same behavior: no GUI is showing, but is showing in processes)

I'm using java 1.7, OS X version: 10.8.5
