JFXPanel can cause the program to not exit

Question

This is a separate issue that came to light in another discussion: [url http://forums.oracle.com/forums/thread.jspa?threadID=2236566]Image conversion between AWT and FX
I've concluded that the culprit is the JFXPanel. Hopefully this will be sorted out by the final release. The minimum code required to reproduce the problem is:import javafx.application.Application;
import javafx.embed.swing.JFXPanel;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class JFXPanelHang extends Application {
  public static void main(String[] args) {
    Application.launch(JFXPanelHang.class, args);
  @Override
  public void start(Stage primaryStage) throws Exception {
    JFXPanel panel = new JFXPanel();
    panel.setScene(new Scene(new Group()));
    primaryStage.setVisible(true);
}The program doesn't terminate when the <tt>Stage</tt> is closed. If however you comment out the <tt>setScene(...)</tt> line, the program terminates normally.
I wanted to log an issue on Jira, but I'm getting an error:

Hi,
If this helps you somehow
here is what i got when listing Threads :
when line setScene... is not commented
java.lang.ThreadGroup[name=main,maxpri=10]
    Thread[main,5,main]
    Thread[JavaFX-Launcher,5,main]
    Thread[QuantumRenderer-0,5,main]
    Thread[JavaFX Application Thread,5,main]
    Thread[Thread-2,5,main]
    Thread[AWT-Shutdown,5,main]
    Thread[AWT-Windows,6,main]
    Thread[AWT-EventQueue-0,6,main]
    Thread[Disposer,10,main]and when it is commented
java.lang.ThreadGroup[name=main,maxpri=10]
    Thread[main,5,main]
    Thread[JavaFX-Launcher,5,main]
    Thread[QuantumRenderer-0,5,main]
    Thread[JavaFX Application Thread,5,main]
    Thread[Thread-2,5,main]
    Thread[Disposer,10,main]same output like in another discussion.
Difference is:
Thread[AWT-Shutdown,5,main]
Thread[AWT-Windows,6,main]
Thread[AWT-EventQueue-0,6,main]
When i close stage those 3 are still running.
