Is the JAR at http://git.tuis.net/jdom/jdom.jar really updated...? I get 
the same result for both cases.

Regarding List<?> I believe that List = List<?> = List<? extends 

Hopefully you should be able to use this code as the basis for a test case:

      TransformerFactory transformerFactory = 
      StreamSource streamSource = new StreamSource(new StringReader(
          "<?xml version=\"1.0\" encoding=\"ISO-8859-1\"?>\n" +
          "<xsl:stylesheet version=\"1.0\" 
xmlns:xsl=\"http://www.w3.org/1999/XSL/Transform\">\n" +
          "  <xsl:template match=\"/\">\n" +
          "    <foo>" +
          "<bar myAttribute=\"myValue\" />" +
          "<ns:bar xmlns:ns=\"http://foo/bar\" myAttribute=\"myValue\" 
ns:attribute2=\"prefixed\" />" +
          "</foo>\n" +
          "  </xsl:template>\n" +
      Transformer transformer = 

      JDOMSource source = new JDOMSource(new org.jdom.Document(new 
      JDOMResult result = new JDOMResult();
      transformer.transform(source, result);
