JList with LineBorder think=2

Question

hello all
i am writing a look and feel .
and when i have a JList with LineBorder with thinness = 2 and a item is selected ,
i cant see the complete text of the selected item
my question is there a simple way to make this work
without changing the list preferred size inside my application ?
thank you
here is an example
(please select the third item 'ccccccccccccccc')
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Component;
import javax.swing.DefaultListCellRenderer;
import javax.swing.JDialog;
import javax.swing.JFrame;
import javax.swing.JList;
import javax.swing.JScrollPane;
import javax.swing.border.LineBorder;
public class DialogTest extends JDialog{
  public DialogTest(JFrame f){
    super(f);
    JList list = new JList(new String[]{"aaaaaaaaaaaa" ,"bbbbbbbbbbbbbbb" ,"cccccccccccccccccc"});
    list.setCellRenderer(new DefaultListCellRenderer(){
      public Component getListCellRendererComponent(JList list, Object value, int index, boolean isSelected, boolean cellHasFocus) {
        if(isSelected){
          setBorder(new LineBorder(Color.GREEN ,2));
        }else{
          setBorder(null);
        setText(value.toString());
        return this;
    setLayout(new BorderLayout());
    add(new JScrollPane(list) ,BorderLayout.CENTER);
    pack();
  public static void main(String[] args){
    DialogTest t = new DialogTest(new JFrame());
    t.setVisible(true);
}

ok, thanks now this works on the demo also for me.
but when settings my UI ,i get same result
i want this border no mater what Render the user will put
this is what i do

  public void installUI(JComponent c){
    super.installUI(c);
    if(c instanceof JList){
      JList listJtpc = (JList)c;
      listJtpc.setCellRenderer(new JTPCListCellRenderer());
  public static ComponentUI createUI(JComponent c) {
    return new JTPCListUI();
  LineBorder m_borderSelected     = new LineBorder (Color.GREEN ,3);
  EmptyBorder m_borderDeselected  = new EmptyBorder(new Insets(3, 3, 3, 3));
   * COPY PASTE CODE FROM PARENT 'BasicListUI' ,IN JAVA VERSION  jdk1.6.0_18
   * Paint one List cell: compute the relevant state, get the "rubber stamp"
   * cell renderer component, and then use the CellRendererPane to paint it.

    if (isFileList) {
      // Shrink renderer to preferred size. This is mostly used on Windows
      // where selection is only shown around the file name, instead of
      // across the whole list cell.
      int w = Math.min(cw, rendererComponent.getPreferredSize().width + 4);
      if (!(list.getComponentOrientation() == ComponentOrientation.LEFT_TO_RIGHT)) {
        cx += (cw - w);
      cw = w;
    rendererPane.paintComponent(g, rendererComponent, list, cx, cy, cw, ch, true);
