JTable methods worked in JDK5 and no more in JDK6

Question

Hi,
I have a JTable child class, with an override method editCellAt. The main goal of this method is to allow select all the cell value and when the user types some char, it changes all the old value. This is very important for users, to easy typing new values in any cell.
These worked very well until JDK5, and it doesn't work in JDK6. Now in JDK6 this code puts the 1st char after other old chars, and then for 2nd char it starts to work fine.
The code for test is here:
package gestor.princ;
import java.util.EventObject;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.border.*;
import javax.swing.table.*;
import javax.swing.text.*;
public class testJTable extends JFrame {
  public static void main(String[] args) {
    testJTable frame = new testJTable();
    Object[][] data =
      {"TesteAAAAAA1","1.2"},
      {"TesteBBBBBB2","3.4"},
      {"TesteCCCCCC3","5.6"},
      {"TesteDDDDDD4","7.8"},
    Object[] columnNames = {"Text","Value"};
    DefaultTableModel model = new DefaultTableModel(data, columnNames);
    selectallJTable table = new selectallJTable(model);
    table.setPreferredScrollableViewportSize(table.getPreferredSize());
    JScrollPane scrollPane = new JScrollPane(table);
    frame.getContentPane().add(scrollPane);
    frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
    frame.pack();
    frame.setLocationRelativeTo( null );
    frame.setVisible(true);
class selectallJTable extends JTable {
  public selectallJTable(AbstractTableModel dataModel) {
    super(dataModel);
    TableCellRenderer highlightRenderer = new SelectAll();
    setDefaultRenderer(Object.class, highlightRenderer);
  //  Select the text when the cell starts editing
  //  a) text will be replaced when you start typing in a cell
  //  b) text will be selected when you use F2 to start editing
  //  c) text will be selected when double clicking to start editing
  public boolean editCellAt(int row, int column, EventObject e) {
    boolean result = super.editCellAt(row, column, e);
    Component editor = getEditorComponent();
    if (editor != null) {
      if (editor instanceof JComboBox)
        editor = ((JComboBox) editor).getEditor().getEditorComponent();
      if (editor instanceof JTextComponent) {
        if (e == null) {
          ((JTextComponent)editor).selectAll();
        } else {
          final Component editor1 = editor;
          SwingUtilities.invokeLater(new Runnable() {
            public void run() {
              ((JTextComponent)editor1).selectAll();
    return result;
  class SelectAll extends DefaultTableCellRenderer {
    private Color selectionBackground = UIManager.getColor("TextField.selectionBackground");
    private Border editBorder = BorderFactory.createLineBorder(Color.BLACK);
    private boolean cellHasFocus;
    public Component getTableCellRendererComponent(
      JTable table, Object value, boolean isSelected,
      boolean hasFocus, int row, int column) {
      super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
      cellHasFocus = hasFocus;
      return this;
    protected void paintComponent(Graphics g) {
      if (cellHasFocus && !getText().equals("")) {
        setBorder( editBorder );
        g.setColor( selectionBackground );
        g.fillRect(0, 0, getPreferredSize().width, getSize().height);
      super.paintComponent(g);
}

I have changed this part of code:
        if (e == null) {
          ((JTextComponent)editor).selectAll();
        } else {
          final Component editor1 = editor;
          SwingUtilities.invokeLater(new Runnable() {
            public void run() {
              ((JTextComponent)editor1).selectAll();
       }by simply:
((JTextComponent)editor).selectAll();Now typing new value works fine. However, selectAll doesn't work anymore. I would like to select all cell value (with blue mark), it's better for user to know what cell is actually selected.
