This problem has to do with the method java.awt.Component.repaint().

According to the spec:
"public void repaint()
      Repaints this component.
      This method causes a call to this component's update method as soon as possible.
"
But with the current implemention, the method repaint() doesn't call the update() method for some light weight component.

See the following code fragment:
=============================================================
 public Status Component2004() {
    
        Frame fr = new Frame();
        FakeComponent fc = new FakeComponent();
        try {
            fr.setSize(200, 200);
            fr.add(fc);
            fr.setVisible(true);
            synchronized (fr) {
                while (!fr.isShowing()) {
                    try {
                        fr.wait(50);
                    } catch (InterruptedException ie) {
                    }
                }
            }
            Graphics g = fc.getGraphics();
            fc.repaint();
            synchronized (fr) {
                while (fc.updateCatch == false) {
                    try {
                        fr.wait(50);
                    } catch (InterruptedException ie) {
                    }
                }
            }
            if (fc.updateCatch == false) {
                return Status.failed("Failed: method did not call the update() method");
            }
            return Status.passed("OKAY");
        } finally {
            fr.dispose();
        }
    }


    class FakeComponent extends Component {
        public boolean paintCatch = false;
        public boolean updateCatch = false;
        
        public void paint(Graphics g) {
            paintCatch = true;
            super.paint(g);
        }
        
        public void update(Graphics g) {
            updateCatch = true;
            super.update(g);
        }
    }
  
===============================================================================

The result of running the above code is that it keeps waiting and stays in while loop.

But if I changed FakeCompoennt extends Canvas instead of Component, the abvoe code passed.
