Hi,

I execute inside a JFrame them operations :
 - From JFrame : Create JDialog
 - From JDialog : Delete JDialog (with dispose())
The consequence is all JDialog remains allocate memory (no passage in the
garbage collector)
For information, if JDialog deleted with system closing (cross highly right)
is ok.
Thanks for your help.

PS: Sample

import java.awt.*;
import java.awt.event.*;
import com.sun.java.swing.*;

public class MyFrame extends JFrame implements ActionListener
{
    public MyFrame()
    {
        super("MyFrame");
        getContentPane().setLayout(new GridLayout(1, 2));
        addWindowListener(new WindowAdapter()
        {
            public void windowClosing(WindowEvent e) {System.exit(0);}
     });

        JButton button1 = new JButton("OPEN DIALOG");
        button1.addActionListener(this);
        button1.setActionCommand("OPEN DIALOG");
        getContentPane().add(button1);

        JButton button2 = new JButton("RUN GC");
        button2.addActionListener(this);
        button2.setActionCommand("RUN GC");
        getContentPane().add(button2);

     pack();
     setVisible(true);
    }

    public void actionPerformed(ActionEvent e)
    {
        if (e.getActionCommand().equals("OPEN DIALOG"))
        {
            new MyDialog(this);
        }
        else if (e.getActionCommand().equals("RUN GC"))
        {
            System.runFinalization();
            System.gc();
        }
    }

    public static void main(String arg[])
    {
        Runtime.runFinalizersOnExit(true);
        new MyFrame();
    }
}

class MyDialog extends JDialog implements ActionListener
{
    public MyDialog(Frame frame)
{
  super(frame, "MyDialog", true);
  addWindowListener(new WindowAdapter()
  {
      public void windowClosing(WindowEvent evt)
      {
          dispose();
      }
  });

  setSize(300,100);
  setLocation(100,100);

  JButton button = new JButton("CLOSE DIALOG");
  button.addActionListener(this);
  button.setActionCommand("CLOSE DIALOG");
  getContentPane().add(button, BorderLayout.CENTER);
  setVisible(true);
}

public void actionPerformed(ActionEvent e)


     dispose();
}

protected void finalize() throws Throwable
{
     System.out.println("dialog.finalize : " + this);
     super.finalize();
}
}
