dropwizard unit test throwing UniformInterfaceException

I know this question must have been asked a thousand times before, but none of the answers at Stackoverflow work for me. I am trying to create a unit test for a restful api which uses basic authentication. Here is the code for API:

@GET
@Timed
@Path("/getAuthPerson/{id}")
@Produces(MediaType.APPLICATION_JSON)
public Person getAuthPerson(@PathParam("id")int id, @Auth Person user) {

    /* use HTTP header:
    Authorization : Basic dGVzdDpzZWNyZXQ=

    For negative test case, use
    Authorization : Basic dGVzdDoxMjM=
     */

    if(user.getName().isEmpty()) {
        return null;
    }

    Person p = new Person();
    p.setName("Test");
    p.setId(0);
    p.setAge(10);

    return p;
}

This API works when I call RESTful client of browser, my IDE or from Fiddler i.e. I am correctly getting 401 when I don't provide auth header/incorrect header and am able to get back the resource when I provide correct header. However, the unit test api refuses to work, here is the code for unit-test:

public class PersonResourceTest {
private static final PersonDao personDao = mock(PersonDao.class);

@ClassRule
public static final ResourceTestRule resources = ResourceTestRule.builder()
        .addResource(new PersonResource(personDao))
        .build();

private static Person getDummyPerson() {
    Person person = new Person();
    person.setName("John Doe");
    person.setBirthDateTime(new DateTime("2012-11-21T13:01:33.568Z"));
    person.setAge(10);
    return person;
}

private final Person person = getDummyPerson();

@Before
public void setup() {
    when(personDao.getPerson(eq(123))).thenReturn(person);
    // we have to reset the mock after each test because of the
    // @ClassRule, or use a @Rule as mentioned below.
    reset(personDao);
}

@Test
public void authenticatedTestGetPositive() {
    PersonDao testDao = mock(PersonDaoMongoImpl.class);
    testDao.createPerson(person);

    WebResource.Builder builder = resources.client().resource("/persons/getAuthPerson/123").getRequestBuilder();
    builder.header("Authorization", "Basic dGVzdDpzZWNyZXQ=");
    //builder.header("Authorization", "Basic dGVzdDoxMjM=");
    builder.accept(MediaType.APPLICATION_JSON);

    Person p = builder.get(Person.class);
    assertThat(p).isEqualTo(person);
    verify(testDao).getPerson(123);
}

}

The unit test which does not involve authentication works perfectly, however this authentication unit test gives this error:

    ERROR [2014-08-10 14:48:58,108] com.sun.jersey.spi.container.ContainerRequest: A message body reader for Java class com.rms.pilotapi.core.Person, and Java type class com.rms.pilotapi.core.Person, and MIME media type application/octet-stream was not found.

You need to register your PersonAuthenticator (or whichever name you used for your Authenticator) in the JUnit testrule (@ClassRule).

The problem is that Jersey tries to deserialize your parameter @Auth Person user, which should be handled by your authenticator.
