Apparently the default behavior of JAXB is to use the context
classloader by default, not the classloader of the specified class(es).
I have found a solution to the problem by replacing:

JAXBContext ctx = JAXBContext.newInstance(Encodings.class);

with:

JAXBContext ctx =
JAXBContext.newInstance(ObjectFactory.class.getPackage().getName(),
ObjectFactory.class.getClassLoader());

(where ObjectFactory is the JAXB ObjectFactory in the same package as
Encodings)

I will publish a snapshot shortly.
