Thanks for your help !!
But I have some other problem now with the finalize() method.
First, I have a JDialog with a JPanel with a JComboBox in it. The combo is
initiated with some items and a listener, something like this :

public class MyDialog extend JDialog {
....
.....
JComboBox m_choiceLangue = new JComboBox(new String("french","english"));
   m_choiceLangue.setSelectedItem("french");
   m_choiceLangue.setPreferredSize(new Dimension(100, 20));
    m_choiceLangue.setLightWeightPopupEnabled(false);
    m_choiceLangue.setFont(m_font);

   ItemListener m_choiceListener = new java.awt.event.ItemListener() {
      public void itemStateChanged(ItemEvent e) { onLangChanged(e);} };
    m_choiceLangue.addItemListener(m_choiceListener);

    JPanel panel3 = new JPanel();
    panel3.setLayout(new FlowLayout(FlowLayout.LEFT,30,2));
    panel3.add(m_textControlLangue);
    panel3.add(m_choiceLangue);

Now if I had the JCombo to panel3 the dialog don't get finalized . When I
comment the last line the dialog get finalized. Is there something that I'm
missing...
Is it a JComboBox bug ?
In the JDialog dispose() and finalize() methods I set the reference objects
to null.

I have a similar strange problem with a JTree. The creation is OK. But when I
add it to the JPanel in the dialog , the dialog is not freed.
Any help would be greatly appreciated.
