JList does not scroll to selected item for setSelectedValue(value, true), but
the item is selected, as can be seen if the user scrolls manually. The attached
code works correctly run under 1.2.2, but does not scroll under 1.3.0 or 1.3.1.

import java.awt.*;
import javax.swing.*;

public class JListBug {

   public static void main(String args[]) {

      JFrame jFrame = new JFrame();
      JPanel jPanel = new JPanel();
      JScrollPane jScrollPane;

      String[] names = { "aaaaa", "bbbbb", "ccccc", "ddddd", "eeeee", "fffff",
                         "ggggg", "hhhhh", "iiiii", "jjjjj", "kkkkk", "lllll",
                         "mmmmm", "nnnnn", "ooooo", "ppppp", "qqqqq", "rrrrr",
                         "sssss", "ttttt", "uuuuu", "vvvvv", "wwwww", "xxxxx",
                         "yyyyy", "zzzzz" };

      JList jList = new JList(names);
      jScrollPane = new JScrollPane(jList);

      jPanel.setLayout(new GridBagLayout());
      jPanel.add(jScrollPane,
                 new GridBagConstraints(0, 0, 1, 1, 0.0, 0.0,
                                        GridBagConstraints.CENTER,
                                        GridBagConstraints.NONE,
                                        new Insets(0, 0, 0, 0),
                                        0, 0));

      jList.setSelectedValue("xxxxx", true); // <---<< Neither of these
      jList.ensureIndexIsVisible(23); // <---<< work under 1.3.0

      jFrame.getContentPane().add(jPanel);
      jFrame.pack();
      jFrame.setVisible(true);
   }
