InsertBeforeEnd works in JDK1.3 but not in JDK1.4

Question

Any idea why this would work perfectly in JDK1.3 but not JDK1.4?
logPane = new JEditorPane();
logPane.setEditable(false);
HTMLEditorKit k = new HTMLEditorKit();
doc = (HTMLDocument)k.createDefaultDocument();
logPane.setEditorKit(k);
logPane.setDocument(doc);
logPane.setText("<div id=\"myDiv\"></div>");
Element convDiv = doc.getElement("myDiv");
doc.setInnerHTML(convDiv,"<p>Test1</p>"); // This works in both
doc.insertBeforeEnd(convDiv,"<p>Test2</p>"); // This throws exception
The setInnerHTML works fine in the JDK's. The insertBeforeEnd throws a "BadLocationException: Invalid insert" in JDK1.4 but works fine in JDK1.3...
Quite frustrating!

Well, I finally took a look at the JDK code (GapContent.java). It seems the supposedly "fixed" bug is still there in JDK1.4.0 and JDK1.4.1 (latest) (http://developer.java.sun.com/developer/bugParade/bugs/4496801.html)
The workaround is to put some characters after the div as follows:
logPane.setText("<div id=\"myDiv\"></div>&_nbsp_;");
( remove the _ in nbsp above )
Now it works in both JDK's!
