I still get the error for applets with this change. For testing I use this class:

package test;

import java.applet.Applet;
import java.awt.Color;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import javax.media.opengl.GL;
import javax.media.opengl.GLAutoDrawable;
import javax.media.opengl.GLCapabilities;
import javax.media.opengl.GLCapabilitiesImmutable;
import javax.media.opengl.GLEventListener;
import javax.media.opengl.GLProfile;
import javax.media.opengl.awt.GLCanvas;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class JoglCanvasTest extends Applet implements GLEventListener {

  public JoglCanvasTest() {
  }

  public static JFrame frame;
  public static JPanel appletHolder;
  public static boolean isApplet = true;

  static public void main(String args[]) {
    Applet myApplet = null;
    isApplet = false;

    myApplet = new JoglCanvasTest();
    appletStarter(myApplet, "JoglCanvasTest", 800, 600);
  }

  static public void appletStarter(final Applet des, String frameName, int width, int height) {
    appletHolder = new JPanel();
    if (frame != null) {
      frame.dispose();
      frame = null;
    }
    frame = new JFrame(frameName);
    frame.setVisible(false);
    frame.getContentPane().add(appletHolder);

    appletHolder.setLayout(null);
    des.setBounds(0, 0, width, height);
    appletHolder.add(des);

    frame.setVisible(true);
    int frameBorderSize = appletHolder.getLocationOnScreen().x - frame.getLocationOnScreen().x;
    int titleBarHeight = appletHolder.getLocationOnScreen().y - frame.getLocationOnScreen().y;
    int frameWidth = width + 2 * frameBorderSize;
    int frameHeight = height + titleBarHeight + frameBorderSize;
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setSize(frameWidth, frameHeight);
    frame.setVisible(true);
    des.init();
    frame.addWindowListener(new WindowAdapter() {
      public void windowClosing(WindowEvent e) {
        System.exit(0);
      }
    });
  }

  public void init() {
    initOpenGLAWT();
  }

  public void initOpenGLAWT() {
    setBackground(Color.gray);
    setLayout(null);

    GLProfile glp = GLProfile.getDefault();
    GLCapabilities caps = new GLCapabilities(glp);
    GLCanvas canvas = new GLCanvas((GLCapabilitiesImmutable) caps);
    canvas.setBounds(50, 50, 200, 450);
    canvas.addGLEventListener(this);
    add(canvas);
  }

  public void init(GLAutoDrawable gLAutoDrawable) {
    GL gl = gLAutoDrawable.getGL();
    gl.glClearColor(1.0f, 0.0f, 0.0f, 1.0f);
    gl.glClear(GL.GL_COLOR_BUFFER_BIT);
    gLAutoDrawable.swapBuffers();
  }

  public void dispose(GLAutoDrawable glad) {
  }

  public void display(GLAutoDrawable glad) {
  }

  public void reshape(GLAutoDrawable glad, int i, int i1, int i2, int i3) {
  }

}

in the jar "JoglCanvasTest.jar". Along with this html ("applet.html"):

I put those two file in the same directory. I have a subdirectory there called 'lib' that there that contains gluegen-rt.jar, jogl-all.jar and the appropriate natives jars. You can either load the html page and run it in a browser or run the class as an application directly ("java -cp JoglCanvasTest.jar:lib\gluegen-rt.jar:lib\gluegen-rt-natives-macosx-universal.jar:lib\jogl-all.jar:lib\jogl-all-natives-macosx-universal.jar test.JoglCanvasTest").

When I open the html page in a browser on OSX 10.6 using Apple's Java 1.6, the box is black and in the lower left (this is the error case).
When I run the applet directly as an application under OSX 10.6 using Apple's Java 1.6 the box is red and in the correct location.

Under Windows the box is always in the correct location and is black as an applet and red as an application.
The color difference is because I'm intentionally not doing anything with the 'reshape'.
