Я работаю над примером с JavaFX 2.2 и Java 8. Я создал этот простой активатор Apache Felix:

Активатор:

import javafx.application.Platform;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;

public class Activator implements BundleActivator
{

    Stage stage;

    @Override
    public void start(BundleContext context) throws Exception
    {

        Platform.runLater(new Runnable()
        {
            @Override
            public void run()
            {
                stage = new Stage();
                BorderPane pane = new BorderPane();
                Scene scene = new Scene(pane, 400, 200);
                pane.setCenter(new Label("This is a JavaFX Scene in a Stage"));
                stage.setScene(scene);
                stage.show();
            }
        });
        System.out.println("Main Module is loaded!");

    }

    @Override
    public void stop(BundleContext context) throws Exception
    {
        Platform.runLater(new Runnable()
        {
            @Override
            public void run()
            {
                stage.close();
            }
        });
        System.out.println("Main Module is unloaded!");
    }
}
