It seems that the method withAnnotiationIntrospector does not set AnnotiationIntrospector. It's returns new DeserializationConfig/SerializationConfig object instead (with correct AnnotiationIntrospector).

So, my version of JaxbJacksonObjectMapper:

public class JaxbJacksonObjectMapper extends ObjectMapper {

    public JaxbJacksonObjectMapper() {
        super();

        final AnnotationIntrospector introspector = new JaxbAnnotationIntrospector();

        this.configure(org.codehaus.jackson.map.DeserializationConfig.Feature.UNWRAP_ROOT_VALUE, true);
        this.configure(org.codehaus.jackson.map.SerializationConfig.Feature.WRAP_ROOT_VALUE, true);

        this.setDeserializationConfig(this.getDeserializationConfig().withAnnotationIntrospector(introspector));
        this.setSerializationConfig(this.getSerializationConfig().withAnnotationIntrospector(introspector));

    }
}

Now it support @XmlRootElement, @XmlTransient and other.
