Problem conclusion
In the creation of the JAXB model, gathering method objects does not take much consideration for class hierarchy. This has potential to cause an attribute which is XML-mapped to a class using JAXB, to not get unmarshalled when the attribute is declared in a parent class. This therefore, can result in a null value being returned instead of an expected value. The issue was fixed by ensuring that the JAXB model keeps a cache of the attributes it processes in both child and parent classes. This adds the intelligence the JAXB model needs to deal with polymorphic attributes. The fix for this APAR is currently targeted for inclusion in fix pack 8.5.5.3.
