Attempt to display URL http://www.snapon.com via JEditorPane.setPage(URL)
results in many EmptyStackExceptions (see trace below).

===============================================
SOURCE CODE to demonstrate problem:

public class TestHTMLRead extends javax.swing.JFrame
    implements java.awt.event.ActionListener
{
// Using JDK1.3 RC3, attempting to display www.snapon.com in a JEditorPane
// results in an EmptyStackException. To see the bug, run this program
// from a command window and load the browser by selecting the "Reload"
// button at the bottom of the window.

    String url = "http://www.snapon.com";
    javax.swing.JEditorPane editorPane;
    javax.swing.JScrollPane scrollPane;
    javax.swing.JButton reloadButton;

    public TestHTMLRead()
    {
            editorPane = new javax.swing.JEditorPane();
            scrollPane = new javax.swing.JScrollPane(editorPane);
            getContentPane().add(java.awt.BorderLayout.CENTER, scrollPane);

            reloadButton = new javax.swing.JButton("Reload");
            reloadButton.addActionListener(this);
            getContentPane().add(java.awt.BorderLayout.SOUTH, reloadButton);
            setSize(750, 425);
    }

    public void reloadBrowser()
    {
        try {
            editorPane.setPage(url);
        } catch (java.io.IOException ex) { ex.printStackTrace(); }
    }

    public void actionPerformed(java.awt.event.ActionEvent event)
    {
        Object source = event.getSource();
        if (source == reloadButton)
        {
            reloadBrowser();
        }
    }

    public static void main(String[] argv)
    {
        (new TestHTMLRead()).show();
    }
}
