Dear List,

First off, a huge thanks to all of those who have kept this project alive. I am a developer from the Unidata IDV team (http://www.unidata.ucar.edu/software/idv/) and we have relied on this project for 10+ years for 3D visualization.

We have been using Java 3D (1.6.0-pre9-daily-experimental daily) on OS X and Java 7 with mostly good results, but we have come across a bug where the behavior of a
Java Swing object (javax.swing.JTabbedPane) is problematic when working with javax.media.j3d.Canvas3D objects. I have attempted to write a minimal example demonstrating this issue:

public class Bug extends JPanel {

    public Bug() {
        super(new GridLayout(1, 1));
        JTabbedPane tabbedPane = new JTabbedPane();
        JPanel      jp1        = new JPanel();
        jp1.setLayout(new BorderLayout());
        jp1.add(canvas3d(1.0f, 1.0f, 0.0f));
        JPanel jp2 = new JPanel();
        jp2.setLayout(new BorderLayout());
        jp2.add(canvas3d(0.0f, 1.0f, 1.0f));
        tabbedPane.addTab("Tab 1", jp1);
        tabbedPane.addTab("Tab 2", jp2);
        add(tabbedPane);
    }

    public static Canvas3D canvas3d(float arg0, float arg1, float arg2) {
        Canvas3D canvas =
            new Canvas3D(SimpleUniverse.getPreferredConfiguration());
        SimpleUniverse universe           = new SimpleUniverse(canvas);
        BranchGroup    root               = new BranchGroup();
        Appearance     polygon1Appearance = new Appearance();
        polygon1Appearance.setColoringAttributes(
            new ColoringAttributes(new Color3f(arg0, arg1, arg2), 1));
        QuadArray polygon1 = new QuadArray(4, QuadArray.COORDINATES);
        polygon1.setCoordinate(0, new Point3f(0f, 0f, 0f));
        polygon1.setCoordinate(1, new Point3f(5f, 0f, 0f));
        polygon1.setCoordinate(2, new Point3f(5f, 3f, 0f));
        polygon1.setCoordinate(3, new Point3f(0f, 3f, 0f));
        root.addChild(new Shape3D(polygon1, polygon1Appearance));
        universe.addBranchGraph(root);
        universe.getViewingPlatform().setNominalViewingTransform();
        return canvas;
    }

    private static void createAndShowGUI() {
        JFrame frame = new JFrame();
        frame.setPreferredSize(new Dimension(200, 200));
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.add(new Bug(), BorderLayout.CENTER);
        frame.pack();
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                createAndShowGUI();
            }
        });
    }
}

When running the Bug.java main application, you will note that switching back and forth between tabs works as expected on Java 3D 1.5 / Java 6 / OS X. However, switching between tabs in Java 3D 1.6 / Java 7 / OS X results in the image contained by the second tab getting stuck no matter what tab you are on.

Again, many thanks for your help.
