Java SE (Java Platform, Standard Edition)

Hello!

I've created dialog which shows TIF image using JIMI library.
I'm invoking dispose() in finalize() method of this dialog. It couse problem with exiting application - System.exit(0) is invoking, but jvm is still working!!! If there is no dispose() in finalize() there is no problem. I check that if I don't use Jimi library everything works fine. It looks like problem with using dll-s (not exactly Jimi library).
I need to invoke dispose() in finalize() (not exactly in this case of course) because I want to be sure that dialog is cleaned up before exit.
Here is code:

import java.awt.*;
import java.awt.event.*;
import java.io.*;
import javax.imageio.stream.FileImageInputStream;
import javax.swing.*;

import com.sun.jimi.core.Jimi;

public class ImageTest extends JFrame {

  public ImageTest() {
    getContentPane().add(new JLabel("Test"));
    pack();
    addWindowListener(new WindowAdapter() {
      public void windowClosing(WindowEvent e) {
        System.out.println("finishing");
        System.exit(0);
      }

    });
    setVisible(true);
    createDialog();

  }

  protected void createDialog() {
    JDialog jd = new JDialog(this, false) {
      protected void finalize() throws Throwable {
        super.finalize();
        dispose();
      }
    };
   // it doesn't change anything
    jd.setDefaultCloseOperation(JDialog.DO_NOTHING_ON_CLOSE);
    jd.getContentPane().setLayout(new BorderLayout());
    try {
      Image img = Jimi.getImage(new FileInputStream("c:\\Temp\\tresc2.tif"));
      jd.getContentPane().add(new JScrollPane(new ImagePanel(img)), BorderLayout.CENTER);
    } catch (Exception x) {
      x.printStackTrace();
    }

    jd.pack();
    jd.setSize(new Dimension(400, 400));
    jd.setLocationRelativeTo(null);
    jd.setVisible(true);
  }

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

  class ImagePanel extends JPanel {

    protected Image img;
    protected int imagePanelWidth, imagePanelHeight;

    ImagePanel(Image img) {
      super();
      this.img = img;
      if (this.img != null) {
        this.imagePanelHeight = img.getHeight(this);
        this.imagePanelWidth = img.getWidth(this);

        setSize(imagePanelWidth, imagePanelHeight);
        setPreferredSize(new Dimension(imagePanelWidth, imagePanelHeight));
      }
    }

    public void paint(Graphics g) {
      super.paint(g);
      Graphics2D g2 = (Graphics2D) g;
      if (img != null)
        g2.drawImage(img, 0, 0, this);
    }

  }
}

"test2.tif" is small TIFF image.
Run class and try to close "test" window - System.exit(0) will invoke but jvm will still run.

Do you have any idea? Is it a java bug?
