JavaTM 2 Platform Std. Ed. v1.4.0 Specification (b71) reads about
JWindow.JWindow(Window,GraphicsConfiguration) constructor:

...
public JWindow(Window owner,GraphicsConfiguration gc)

  Creates a window with the specified owner window and GraphicsConfiguration of a screen
  device. If owner is null, the shared owner will be used and this window will not be
  focusable.

  Parameters:
    owner - the window from which the window is displayed
    gc - the GraphicsConfiguration that is used to construct the new window with; if gc
         is null, the system default GraphicsConfiguration is assumed, unless owner is also
         null, in which case the GraphicsConfiguration from the shared owner frame will be
         used.

 Throws:
   IllegalArgumentException - if gc is not from a screen device. This exception is always
   thrown when GraphicsEnvironment.isHeadless() returns true
...

Here is a code fragment from JDK1.4.0-beta-b71 source code:

-------------------- src/javax/swing/JWindow.java --------------------
...
079> public class JWindow extends Window implements Accessible, RootPaneContainer
080> {
...
167> public JWindow(Window owner, GraphicsConfiguration gc) {
168> super(owner == null ? (Window)SwingUtilities.getSharedOwnerFrame() :
169> null, gc);
170> windowInit();
171 }
...
554> }
---------------------- src/java/awt/Window.java ----------------------
...
342> public Window(Window owner, GraphicsConfiguration gc) {
343> this(gc);
344> ownedInit(owner);
345> }
346>
347> private void ownedInit(Window owner) {
348> if (owner == null) {
349> throw new IllegalArgumentException("null owner window");
350> }
...
354> }
...
----------------------------------------------------------------------

This fragment shows that JWindow(Window owner,GraphicsConfiguration gc) constructor
always throws IllegalArgumentException if "owner" argument is not null.

The following test example demonstrates the bug:

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

public class test {
    public static void main(String argv[]) {
        Window anOwner = null;
        try {
            anOwner = new JWindow();
        } catch (Exception e) {
            System.out.println(e);
            return;
        }

        try {
            JWindow win = new JWindow(anOwner, anOwner.getGraphicsConfiguration());
            System.out.println("Owner is not null: PASS. ");
        } catch (IllegalArgumentException e) {
            System.out.println("Owner is not null: FAIL. "+e);
        }
        try {
            JWindow win = new JWindow(null, anOwner.getGraphicsConfiguration());
            System.out.println("Owner is null: PASS. ");
        } catch (IllegalArgumentException e) {
            System.out.println("Owner is null: FAIL. "+e);
        }
    }
}

Sample output is:
...
$ /net/linux-15/export/home/java/jdk1.4.0/linux/bin/java -Xfuture test
Owner is not null: FAIL. java.lang.IllegalArgumentException: null owner window
Owner is null: PASS.

How to reproduce:
====================
Run the following script under RedHat Linux 6.2
(probably, you need to change JCK and JAVA_HOME paths):
--------Script START---------------------
#!/bin/sh
JAVA_HOME=/net/jdk/export/disk8/local.java/jdk1.4/linux-i386
JCK=/net/jdk/export/disk8/local.java/jck1.4/JCK-runtime-14
export CLASSPATH="$JCK/classes:$JCK/javatest.jar"
executeClass="javasoft.sqe.tests.api.javax.swing.JWindow.Ctor2Tests -TestCaseID JWindow0015"
$JAVA_HOME/bin/java ${executeClass}
---------Script END----------------------

Test output:
=============
JWindow0015: Failed. IllegalArgumentException thrown incorrectly in NOT headless implementationjava.lang.IllegalArgumentException: null owner window
