A DESCRIPTION OF THE REQUEST :
Scenario: javax.swing.JOptionPane is used to display a choice from an Object[] of size 20+ and javax.swing.plaf.basic.BasicOptionPaneUI uses a JList/JScrollPane to display the choices with 10 visible rows.

If keys a-z are used to select a non-visible item then the item is not made visible. The selected item should be made visible.

JUSTIFICATION :
Makes JOptionPane more friendly to use with keyboard with 20+ options.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Ensure the item selected in the JList is always made visible.

e.g. in javax.swing.plaf.basic.BasicOptionPaneUI.getMessage() add something like:

list.addListSelectionListener(new javax.swing.event.ListSelectionListener()
{
  public void valueChanged(ListSelectionEvent e)
  {
    JList list = (JList) e.getSource();
    list.ensureIndexIsVisible(list.getSelectedIndex());
  }
});

---------- BEGIN SOURCE ----------
import javax.swing.JOptionPane;

public class JOptionPaneTest
{
  public static void main(String[] args)
  {
    String[] options = {"a","b","c","d","e","f","g","h","i","j","k","l","m",
                        "n","o","p","q","r","s","t","u","v","w","x","y","z"};

    JOptionPane.showInputDialog(null,
      "select a letter using keys a-z and note that it is not made visible",
      "JOptionPaneTest",
      JOptionPane.INFORMATION_MESSAGE,
      null,
      options,
      options[0]);
  }
}
