I want to hide application window in JavaFX 2.0, calling hide() on Stage object terminate application. How to hide main window and left application running?

import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;


public class SysTray extends Application {

	public static void main(String[] args) {
		Application.launch(SysTray.class, args);
	}

	@Override
	public void start(final Stage s) throws Exception {
		Group rootGroup=new Group();
		Scene scene=new Scene(rootGroup, 800, 600);
		s.setScene(scene);

		Button hide=new Button("hide");
		hide.setOnAction(new EventHandler<ActionEvent>() {
			@Override
			public void handle(ActionEvent paramT) {
				s.hide();
			}});

		BorderPane mainPane=new BorderPane();
		mainPane.setCenter(hide);

		scene.setRoot(mainPane);
		s.setVisible(true);
	}

}
