JEDitorPane fails to display a page (www.snapon.com), which is a hierarchy of
FrameSets, and after attempting to do so, produces many
IndexOutOfBoundsExceptions, from which the application never recovers. Note: In
my application code I was able to verify that most, if not all, of the page was
parsed as I was able to display its structure as a tree, but nothing was ever
displayed in the JEditorPane. Other pages with FrameSets work fine.


SOURCE CODE to demonstrate problem:

public class TestHTMLRead extends javax.swing.JFrame
    implements java.awt.event.ActionListener
{
// Using JDK1.3 RC3, I can't display www.snapon.com in a JEditorPane and
// after attempting to do so, I get many IndexOutOfBoundsExceptions when
// I move the mouse pointer within the JEditorPane. To demonstrate, run
// this program, which should display the page, but doesn't. Then select
// "Reload" button at the bottom of the page. After this, move the mouse
// pointer in the JEDitorPane window and you should see the exceptions
// in the console 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();
    }
}
