      JDK : JDK1.4.0-beta-b71
      JCK : JCK1.4-b06
      Platform[s] : RedHat Linux 6.2, Windows 2000, Windows NT, Windows 98
      switch/Mode : -client -Xmixed
      JCK test owner : http://javaweb.eng/jck/usr/owners.jto
      Failing Test : api/javax_swing/JWindow/index.html#Ctor2 [TestCaseID JWindow0015]

      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.
      ...

      Test source location:

      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
      STATUS:Failed.tests: 1; failed: 1; first test case failure: JWindow0015

      Specific Machine Info:

      Hostname: linux-14
      OS: RedHat Linux 6.2

      Hostname: Linux-2
