Details:

Steps to reproduce:
1. Compile and run the attached testcase

Expected results (sun's java 1.5.0):
1. A window shows up. It has filechooser components and "label0" below them.

Actual results (classpath 2005-05-30):
1. No window is shown and the following exception is thrown:
java.lang.IllegalArgumentException
   at java.awt.GridBagLayout.addLayoutComponent (GridBagLayout.java:132)
   at java.awt.Container.addImpl (Container.java:382)
   at java.awt.Container.add (Container.java:290)
   at gridbag.<init> (gridbag.java:11)
   at gridbag.main (gridbag.java:6)

Testcase:
import javax.swing.*;
import java.io.*;
import java.awt.BorderLayout;
public class gridbag extends JFrame {
        public static void main(String[] args) {
                (new gridbag()).show();
        }
        public gridbag() {
                JFileChooser fileChooser = new JFileChooser();
                JLabel label = new JLabel("label0");
                fileChooser.add(label, BorderLayout.SOUTH);
                fileChooser.showOpenDialog(this);
        }
}

I am not sure if this is a bug. 
http://java.sun.com/j2se/1.4.2/docs/api/java/awt/GridBagLayout.html#addLayoutComponent(java.awt.Component,
java.lang.Object) suggests that the exception must be thrown but sun's own
java does not seem to do that. Should we
1) make classpath not throw the exception and violate the javadoc
or
2) try to fix all free software projects that depend on the incorrect
behavior?
