Bug 889

I wrote a code to move a GLCanvas from a JFrame to another and move it back to the first. If I do this operation more than one time the GLCanvas disappear.
I Experienced this problem with version 2.1.2 on windows 7 x64 platform. With jogl 2.0.2 the problem doesn't appear. 

This is the application:

import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.media.opengl.GLCapabilities;
import javax.media.opengl.GLProfile;
import javax.media.opengl.awt.GLCanvas;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.WindowConstants;

    public JoglFrameError() {

        GLProfile profile = GLProfile.get(GLProfile.GL2);
        GLCapabilities glCapabilities = new GLCapabilities(profile);
        final GLCanvas glCanvas = new GLCanvas(glCapabilities);
        final JPanel container = new JPanel(new BorderLayout());
        container.add(glCanvas);

        setLayout(new BorderLayout());
        // create a button that open a new JFrame and move the GLCanvas
        JButton button = new JButton("Move GlCanvas to new Frame");
        button.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(java.awt.event.ActionEvent evt) {                
                final JFrame newFrame = new JFrame();

                // Create a button that move back the GLCanvas to the first frame
                JButton closeBt = new JButton("Move Back the GLCanvas");
                closeBt.addActionListener(new ActionListener() {

                    @Override
                    public void actionPerformed(ActionEvent e) {
                        container.add(glCanvas, BorderLayout.CENTER); 
                        glCanvas.setBounds(0,0, container.getSize().width, getSize().height);
                        newFrame.dispose();
                    }
                });

                newFrame.setSize(320, 240);
                newFrame.setLayout(new BorderLayout());
                newFrame.add(closeBt, BorderLayout.NORTH);
                newFrame.add(glCanvas, BorderLayout.CENTER);                
                newFrame.setVisible(true);

            }
        });

        add(button, BorderLayout.NORTH);
        add(container, BorderLayout.CENTER);
        setSize(640, 480);
        setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
    }
