GUI problem with JTable..( bug_id=4940522)

Question

its found that the mouse event is not recognised on empty table when using with java 1.4.2. Please specify if there is any chnge done for mouse event capture for table from java 1.3.1 to java 1.4.2.
actually its a bug in java 1.4.2 ( ref. bug_id=4940522 )
here is the code reference..
public class TableEditor extends JPanel
implements ListSelectionListener, Selector, Editor
private JTable myTable;
private JPopupMenu myPopup;
private Vector myActions;
private Vector myListeners;
public TableEditor(String anAssociation, Editor anEditor, int type)
super(new GridLayout(1,1));
myListeners = new Vector();
myActions = new Vector();
myPopup = new JPopupMenu();
myTable = new JTable();
myTable.getSelectionModel().addListSelectionListener(this);
myTable.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent me)
if ((me.getModifiers() & MouseEvent.BUTTON3_MASK) != 0)
// Update actions in case ListSelectionModel are out of sync.
for (int i = 0; i < myActions.size(); i++)
Object o = myActions.elementAt(i);
if (o instanceof SelectorAction)
((SelectorAction)o).check();
myPopup.show(myTable, me.getX(), me.getY());
// Added mouse listener to JTableHeader
// This is a temporary solution to open popup menu on blank table,
// as in Java 1.4.2 no mouse event captured on blank table.
// So for now we will capture the event from the table header.
JTableHeader myTableHeader = myTable.getTableHeader();
myTableHeader.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent me)
if ((me.getModifiers() & MouseEvent.BUTTON3_MASK) != 0)
// Update actions in case ListSelectionModel are out of sync.
for (int i = 0; i < myActions.size(); i++)
Object o = myActions.elementAt(i);
if (o instanceof SelectorAction)
((SelectorAction)o).check();
myPopup.show(me.getComponent(), me.getX(), me.getY());
The solution given is temporary ( adding JTableHeader component)..
we want to retain the same functionality .. mouse event should get captured on empty table only..
