Review ID 94817 said my bug didn't work on Solaris. It's right,
and I'm wrong. It only produces a bug on Windows 98,
maybe 95 also, but I don't know.

====================== Incident ID #94817 ==================

java version "1.3beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3beta-O)
Java(TM) HotSpot Client VM (build 1.3beta-O, mixed mode)

java full version "1.3beta-O"


When you attempt to show a java.awt.Window constructed
using the empty constructor, it throws a NullPointerException.
By the way, is the output for errors being printed backwards?


import java.awt.*;
import java.awt.event.*;

public class asdf {
public static void main (String[] args) {
Window f = new Window();
f.setSize(300,300);
        f.addWindowListener(new WindowAdapter() {
            public void windowIconified(WindowEvent e) {
                Window w = e.getWindow();
                w.toFront();
            }
        });
f.setVisible(true);
}
}

------Causes NullPointerException:
Exception in thread "main" java.lang.NullPointerException: peer
