[jdom-interest] JDOMSource and JDOMResult can produce nothing!

[Laurent Bihanic]

You stylesheet generates ill-formed XML: The output misses a document root 
element as signaled by the java.util.EmptyStackException thrown by SAXHandler. 
Thus, JDOMResult is unable to build a JDOM document from the XLST processor 
output.

Once I changed the first template to:
   <xsl:template match="/">
<root>
    <xsl:apply-templates/>
</root>
   </xsl:template>
your example runs fine.

Please note that XMLOutputter can not output HTML, only XML, and that the 
<xsl:output ... /> tag only applies when the XSLT processor performs itself 
the output to a StreamResult.
