What's happening is that for some reason the Oracle SAX parser is giving
a callback for a PI whose target is "xml", and that's an illegal target
per the XML spec so JDOM refuses to accept it.  My guess is the Oracle
parser is treating the document declaration <?xml version="1.0"?> as if
it was a PI because it looks like a PI even though doc decls explicitly
aren't PIs per the XML spec.  Most SAX handlers wouldn't notice this, so
Oracle probably hasn't heard of the bug, but JDOM does well-formedness
checking so this exposes their bug.
