  To produce the problem, I just have to execute a simple awt based program. The
same could be done just executing the appletviewer. I've removed all PATH,
CLASSPATH, LD_LIBRARY_PATH, and JAVA_HOME variables, and even installed the JDK
in a different directory with no avail. I've looked for a patch that might fix
this but none seem to address it. The display is going to a remote PC running
Exceed x-emulation. I've also had the same results with X-Win32. From the
console, displayed output does not segmenentation fault but the display is
turned black and must continually be refreshed to be seen. The source code is a
follows:

import java.awt.*;

public class Frame1 extends Frame
{
public Frame1()
{
setLayout(null);
setSize(405,305);
setVisible(false);
setTitle("AWT Application");
}

public Frame1(String title)
{
this();
setTitle(title);
}

    public void setVisible(boolean b)
{
if(b)
{
setLocation(50, 50);
}
super.setVisible(b);
}

static public void main(String args[])
{
try
{
     (new Frame1()).setVisible(true);
}
catch (Throwable t)
{
System.err.println(t);
t.printStackTrace();
System.exit(1);
}
}

public void addNotify()
{
Dimension d = getSize();
super.addNotify();
if (fComponentsAdjusted)
return;
setSize(getInsets().left + getInsets().right + d.width,
getInsets().top + getInsets().bottom + d.height);
Component components[] = getComponents();
for (int i = 0; i < components.length; i++)
{
Point p = components[i].getLocation();
p.translate(getInsets().left, getInsets().top);
components[i].setLocation(p);
}
fComponentsAdjusted = true;
}
boolean fComponentsAdjusted = false;
}



The output looks like this:

This appears to be a regression of bug 4219633 (duplicate of 4219215, closed).

I am building a simple JComboBox. The attached code is simplified from
the Java Tutorial example ComboBoxDemo.java. This code causes a SEGV.
The SEGV is hard to reproduce -- happens only about one time out of ten.

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class Combo extends JPanel
{
   public static void main( String s[])
   {
      // Create the frame.
      JFrame frame = new JFrame( "Combo" );
      frame.addWindowListener( new WindowAdapter()
      { public void windowClosing( WindowEvent e )
         { System.exit( 0 );
         }
      });
 
      // Create the combo box.
      String[] petStrings = { "Bird", "Cat", "Dog", "Rabbit", "Pig" };
      JComboBox petList = new JComboBox( petStrings );
// petList.setEditable( true );
      frame.getContentPane().add( petList );

      // Show the frame.
      frame.pack();
      frame.setVisible( true );
   }
}


The SEGV traceback varies but is usually like the following:
