It seems that JAXB silently ignores incorrect values of enum types. The
following short program demonstrates this issue. Instead of producing a
parsing mistake like "Cannot parse 'WRONG' as a value of enum type 'Color'"
JAXB unmarshaller simply sets Color to null.


public class JAXBTest {

        @XmlRootElement
        public enum Color {
                Red, Green
        }

        public static void main(String[] args) throws Exception {
                JAXBContext context = JAXBContext.newInstance(Color.class);

                printColor(context, "<color>Red</color>");
                printColor(context, "<color>Green</color>");
                printColor(context, "<color>WRONG</color>");
        }

        private static void printColor(JAXBContext context, String xml)
                        throws JAXBException {
                Unmarshaller um = context.createUnmarshaller();
                Color color = (Color) um.unmarshal(new StringReader(xml));
                System.out.println("Color:" + color);
        }
}

Best Regards,
