`@JsonAppend` causes 'IllegalStateException` `Unsupported annotated member' with `JaxbAnnotationModule`

[asodja]

It seems that using JaxbAnnotationModule causes some problems when using @JsonAppend feature. Example that reproduce the issue:

@Test
public void testJsonAppendWithJaxb() throws Exception {
    ObjectMapper mapper = new ObjectMapper();
    mapper.registerModule(new JaxbAnnotationModule());
    String json = mapper.writeValueAsString(new Pojo("foo"));
    assertEquals("{\"name\":\"foo\",\"virtual\":\"bar\"}", json);
}

@JsonAppend(props = @JsonAppend.Prop(name = "virtual", value = MyVirtualPropertyWriter.class))
public static class Pojo {

    private final String name;

    public Pojo(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }
}

public static class MyVirtualPropertyWriter extends VirtualBeanPropertyWriter {
    public MyVirtualPropertyWriter() {
    }

    protected MyVirtualPropertyWriter(BeanPropertyDefinition propDef, Annotations contextAnnotations,
            JavaType declaredType) {
        super(propDef, contextAnnotations, declaredType);
    }

    @Override
    protected Object value(Object bean, JsonGenerator jgen, SerializerProvider prov) throws Exception {
        return "bar";
    }

    @Override
    public VirtualBeanPropertyWriter withConfig(MapperConfig<?> config, AnnotatedClass declaringClass,
            BeanPropertyDefinition propDef, JavaType type) {

        return new MyVirtualPropertyWriter(propDef, declaringClass.getAnnotations(), type);
    }
}

Throws exception:

Also changing primary and secondary annotation introspector with:

AnnotationIntrospector jacksonAnnIntro = new JacksonAnnotationIntrospector();
AnnotationIntrospector jaxbAnnIntro = new JaxbAnnotationIntrospector();
mapper.setAnnotationIntrospector(AnnotationIntrospector.pair(jacksonAnnIntro, jaxbAnnIntro));

and it does not work.

I tested it with 2.9.1 and 2.8.8.
