java full version "1.3.0rc3-Z"

I have been using a JTable with a "MultilineHeaderRendere as described in
Chapter 19 of
Graphic Java 2, Volume 2 by David M. Geary.

This allow a table header to grow to multiple crows as the column gets resized.
JDK 1.2
This worked fine, but in 1.3 it stopped working. Any ideas why?



Thanks for you Help.

Here is the sample code from the book. IN JDK 1.2 if you resize the last
column, the table header will always display the entire header (taking up as
many rows as needed. In JDK 1.3, the header gets clipped as the column shrinks.

import javax.swing.*;
import javax.swing.border.*;
import javax.swing.table.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;

public class Test extends JFrame {
String longTitle = "Last Name\nMaiden Name (if divorced)";
MultilineHeaderRenderer multilineRenderer =
new
MultilineHeaderRenderer(longTitle);

JTable table = new JTable(
new Object[][] {
{ "Lynn", "M.", "Seckinger" },
{ "Carol", "R.", "Seckinger" },
{ "Roy", "D.", "Martin" },
{ "Richard", "A.", "Tattersall" },
{ "Philip", "B.", "Edwards" },
{ "Moore", "T.", "Moore" },

// shorten scrollbar grip with these ...

{ "Lynn", "M.", "Seckinger" },

new Object[] {"First Name", "MI", longTitle});

public Test() {
TableColumn middleColumn = table.getColumn("MI");

lastColumn.setHeaderRenderer(multilineRenderer);
table.getTableHeader().setToolTipText("Table Header!");

new JScrollPane(table),
