JTextPane and the direction of "textflow"

Question

Hi, I got a kinda strange question.
What i want to do is to make the text in a JtextPane go from bottom and move up. The textpane wont be editable for the user.
That is: The text should show up at the bottom of the view and move up in the view as more text is added.
I could solve this somewhat unintelligent by adding an invisible box (Box.createVerticalStrut ) at the beginning of the text. The height would be the same as the viewport the textpane is inside. But are there more elegant solution? Scrollbars would be added as soon as the first line is entered into the textpane, and thats a less than ideal solution.

A little more background...
I traced a paste event all the way through, and I'm getting the fatal error at line 231 in HTMLEditorKit:
    public void read(Reader in, Document doc, int pos) throws IOException, BadLocationException {
     if (doc instanceof HTMLDocument) {
         HTMLDocument hdoc = (HTMLDocument) doc;
         Parser p = getParser();
         if (p == null) {
          throw new IOException("Can't load parser");
         if (pos > doc.getLength()) {
          throw new BadLocationException("Invalid location", pos);
         ParserCallback receiver = hdoc.getReader(pos);
         Boolean ignoreCharset = (Boolean)doc.getProperty("IgnoreCharsetDirective");
         p.parse(in, receiver, (ignoreCharset == null) ? false : ignoreCharset.booleanValue());
         receiver.flush();
     } else {
         super.read(in, doc, pos);
    }Line 231 is the receiver.flush() call, at which point a RuntimeException is thrown and caught at line 212 in the EventDispatchThread class pumpOneEventForHierarchy method.
C'mon guys - this has got to be a bug! I traced while pasting some text from Notepad and that went fine. Then I pasted from Mozilla, and got the above. I can't see the state of the objects in the core Java classes (can't seem to get JBuilder to show that), but that's what's happening.
I'm going to hit post on this now, and then stop runtime debugging on JBuilder and watch my computer reboot. Can anyone shed some light on this???
