      • PLATFORM_DEFAULT_FACTORY_CLASS

        private static final java.lang.String PLATFORM_DEFAULT_FACTORY_CLASS
        When JAXB is in J2SE, rt.jar has to have a JAXB implementation. However, rt.jar cannot have META-INF/services/javax.xml.bind.JAXBContext because if it has, it will take precedence over any file that applications have in their jar files.

        When the user bundles his own JAXB implementation, we'd like to use it, and we want the platform default to be used only when there's no other JAXB provider.

        For this reason, we have to hard-code the class name into the API.
