Launching next application on Win7 2.0.2b06


package testproject;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.HBox;
import javafx.stage.Modality;
import javafx.stage.Stage;

/**

public class Main3 extends Application{

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

    @Override
    public void start(Stage stage) throws Exception {
        Button button = new Button("Some button");
        HBox hb = new HBox();
        hb.getChildren().add(button);

        Button button1 = new Button("Some button 2");
        HBox hb1 = new HBox();
        hb1.getChildren().add(button1);

        Scene scene = new Scene (hb, 300, 300);
        stage.setScene(scene);
        stage.show();

        Stage someStage = new Stage();
        Scene oneMoreScene = new Scene(hb1, 300, 300);
        someStage.setScene(oneMoreScene);
        
        someStage.initModality(Modality.NONE);
        someStage.initOwner(stage);
        someStage.show();
        Thread.sleep(5000);
        stage.close();
        System.out.println("Boom");
        someStage.close();
    }
}

Gives as result of execution:

run:
Boom
BUILD SUCCESSFUL (total time: 5 seconds)

If launch the same code on MacOSX 10.6.8 2..0.2b06 I can get an exception as written in comments:
