The woodstox dependency is incompatible with the rest of the XML API due to
a bug in the JDK that is otherwise hidden in all cases in the default

Specifically it's implementation of EndElement brings that bug to the
forefront, when
tries to typecast a Namespace to String.

In the default implementation, that Namespace iterator is always empty, so
it never reaches that line.

Though that does make me wonder why the Document after being read is
scanned again as a DOMSource and then converted back to a Document object.
Might be a better way to pass it on altogether. Makes me wish I had noticed
the deprecation note on org.hibernate.boot.MetadataSources.addDocument(
