JDialogs get not gc'ed.
Compile this little program will demonstrate this.
When running this program on an earlier version of swing the JDialog will
properly garbage collected.
This is a serious bug!!! Pleas fix this soon or provid a workaround.
Any serious program with dialogs will run out of memory very soon!!!!

import java.awt.event.*;

import javax.swing.*;

public class JDialogMemoryBug extends JDialog {

    /** Creates new JDialogMemoryBug */
    public JDialogMemoryBug() {
        JPanel panel = new JPanel();
        JButton closeButton = new JButton("Close");
        panel.add(closeButton);
        closeButton.addActionListener(new ActionListener() {
            
            public void actionPerformed(ActionEvent evt) {
                setVisible(false);
                dispose();
            }
        });
        setContentPane(panel);
        setModal(true);
    }

    public void finalize() {
        System.out.println("FINALIZED");
    }
    
    public static void main(String[] args) {
        while (true) {
            JDialogMemoryBug dialog = new JDialogMemoryBug();
            dialog.pack();
            dialog.setVisible(true);
            dialog = null;
            System.gc();
        }
    }
}
