Runtime error when using MediaTracker

[Bjorn Sandberg]

I have a class which basically does this: (this is pseudo-code)

class GraphicsClass extends Canvas implements a lot of stuff {
Image img;

paint(Graphics g) {
  if (needsupdate)
    paintMyStuff();
  g.drawImage(img,0,0,this);
}

paitMyStuff() {
  MediaTracker tracker = new MediaTracker(this);
  for (list of files) {
     String str = new File(file).getAbsolutePath();
     Image myImage = Toolkit.getDefaultToolkit().createImage(str);
     tracker.addImage(myImage,1);
  }
  try { tracker.waitForAll(); } catch (InterruptedException e) { return; }
  for (list of fetched images)
    img.getGraphics().drawImage(img,x,y,this);
}
}

The problem I get is this: 
First of all, none of the images show up.
Secondly, after the paint function ends, I get a runtime error:

java.lang.NullPointerException
        at java/awt/MediaTrackerEntry.imageUpdate(286)
        at java/awt/Image.stateChange(527)
        at java/awt/Image.createFromFile(382)
        at java/awt/Image$Initializer.startProduction(259)
        at java/awt/Image$Initializer.run(191)
        at java/lang/Thread.run(122)

The code works fine under JDK. I've tried replacing the original classpath
so it will use the Kaffe jar files, but the bug persists.
Kaffe version is 1.0.b1-1.
