Description

FallbackTypeConverter method throws JAXBException when marshalling nested, non-ObjectFactory, JAXB annotated, classes. These are classes that are annotated with the @XmlRootElement, but not generated using XJC, so there is no ObjectFactory class for them. The intention is to provide the package names containing the jaxb.index files to build the context.

FallbackTypeConverter does not marshal or unmarshal using the package names, but rather uses the value's Class as the context. Thus everytime a JAXB annotated object contains another JAXB annotated object, there is an exception that looks like this:
