Can you create a scenario to send me that recreates the situation?

We have encountered a knarly classloading problem that appears to have been

Because of the well-known problems with JAXB using the thread context
classloader by default, the enterprising souls here modified the
javax.xml.bind bundle manifest to include "DynamicImport-Package: *", and
then the JAXBContext is created using:
context = JAXBContext.newInstance(paths.toString(),
JAXBContext.class.getClassLoader());
Not the most elegant solution, but we've been getting by. Until we tried to
upgrade to 3.2.1, when we started seeing:

We went all the way back to 3.0.4 before this error disappeared. The
relevant lines in JAXBContextImpl in this particular version are shown
below. It seems that the DatatypeConverter class might be the issue,
although that appears to be imported from javax.xml.bind. Any insight you
guys can offer would be appreciated. We're stuck on 3.0.4 until we can
resolve this (classloader humour).
