[jdom-interest] Possible BUG in XercesErrHandler class

[Jason Hunter]

Any behavior is fine from my perspective.  This should only affect
someone building a JDOM tree from a file/stream/url using DOMBuilder,
which should be no one since SAXBuilder is a much faster way to do such
a build.

Brett, you wrote the code.  Do you have a preference?
