You can see the detailed description as well as minimized standalone test to illustrate the
problem in the bug report 4301193. The bug #4301193 has been incorrectly closed as the duplicate
of 4370840. The 4370840 was fixed but the fix has been broken after fix of another bug #4392721.
As a result, the javadoc comment for JWindow(Window owner, GraphicsConfiguration gc) now says:

(see delta 1.38 for JWindow.java,
javadoc comments for public JWindow(Window owner, GraphicsConfiguration gc)):
--------------------- JWindow.java -----------------------
...
     * @exception java.lang.IllegalArgumentException if <code>owner</code>
     * is <code>null</code>. IllegalArgumentException if
     * <code>gc</code> is not from
     * a screen device. This exception is always thrown
     * when GraphicsEnvironment.isHeadless() returns true
...
----------------------------------------------------------

But at the same time JWindow(GraphicsConfiguration gc) is implemented as:

--------------------- JWindow.java -----------------------
...
 public JWindow(GraphicsConfiguration gc) {
        this((Frame)null, gc);
    }
...
----------------------------------------------------------

So it will throw IllegalArgumentException regardless of the GraphicsConfiguration passed.
