[jdom-interest] malformed URL exception exception in saxbuilder.build due to unreachable URL

[Oliver Ruebenacker]

     Hello,

  I don't know anything about SAX, but the error says the problem is
not an unreachable URL, but a malformed one. Somehow, it seems to try
to use "<?xml version="1.0"?>" as an URL. Apparently, the content of
an XML file (or the first line of it) is used where a URL should be
used.

     Take care
     Oliver
