How are you creating a JAXBContext? I suspect that the JAXBContext
doesn't know about your IntegerProperty class. If it only knows about
Property, it tries to handle every Property-derived class as a Property,
hence it will only marshal the description.
If so, add IntegerProperty.class as an argument to JAXBContext.newInstance
