When I run the attached program, which create 3 Frame object, each of them running a separate thread to repaint its client zone, I get the following Exception.

This occur with the 1.1.4 version of java, only on Solaris (I tested it on NT, and it was OK)

The test program follows :

import java.util.*;
import java.awt.*;

public class test extends Frame implements Runnable{

   Image toto;
   Thread snoopy;
   int sx=250;
   int sy=100;
   Color c;

   test(Color c){
      setSize(sx,sy);
      setVisible(true);
      snoopy=new Thread(this);
      snoopy.start();
      this.c=c;
   }

   public synchronized void paint(Graphics g){
      if (toto!=null){
spaint(g);
      }
   }

   public synchronized void spaint(Graphics g){
      g.drawImage(toto,0,0,null);
   }

   public void run(){
      toto=createImage(sx,sy);
      Graphics g=toto.getGraphics();

      while(true){
try{
snoopy.sleep(10);
         }catch(InterruptedException e){
e.printStackTrace();
         }
         draw(g);
repaint();
      }
   }

   public synchronized void draw(Graphics g){
      g.setColor(c);
      g.fillRect(0,0,sx,sy);
      g.setColor(Color.black);
      g.drawString((new Date()).toString(),5,sy/2);
   }

   public static void main(String arg[]){
      test Testa=new test(Color.red);
      test Testb=new test(Color.green);
      test Testc=new test(Color.blue);
   }
}
