[jdom-interest] Possible bug in SAXHandler when "namespaces" feature is off

I've noticed that if I turn off the "namespaces" feature, JDOM fails with
the following exception:

Caused by: org.jdom.IllegalNameException: The name "" is not legal for
JDOM/XML elements: XML names cannot be null or empty.
   at org.jdom.Element.setName(Element.java:217)
   at org.jdom.Element.<init>(Element.java:145)

   at org.jdom.input.SAXBuilder.build(SAXBuilder.java:370)
   at org.jdom.input.SAXBuilder.build(SAXBuilder.java:684)

The problem is in SAXHandler in this line:
    element = factory.element(localName);

In fact, the parser passes the name not through the localName parameter, but
through the qName parameter.
Thus, IMO, it should read
    element = factory.element(qName);

Am I making any sense?
