Sample Program


import java.applet.*;
import java.awt.*;

public class sample1 extends Applet implements Runnable
{
public static void main(String args[])
{
Frame frame = new Frame("sampleFrame");

frame.show();
frame.hide();
}

public void run()
{
}
}



The Problem

To demonstrate the problem, run "jdb sample1" and then enter the
following jdb commands:


   stop in sample1.main
   run
   next
   dump Frame



The dump command will cause a crash in java_g.exe with an invalid memory
reference.
