Web Service Testing with Arquillian

I'm doing a unit test class and I'm using Arquillian because of the CDI, in this case I'm testing a Web Service for authentication of company users. Here is the source of the test class:

@RunWith(Arquillian.class)
public class UsuarioWebServiceTest {

/**
 * Criando o arquivo de deploy do arquillian.
 * 
 * @return JavaArchive
 */
@Deployment
public static WebArchive createTestArchive() {
    return ShrinkWrap.create(WebArchive.class, "consisanet-aut-web.war")
            .addPackages(true, Usuario.class.getPackage())
            .addPackages(true, UsuarioDAO.class.getPackage())
        .addPackages(true, JPAUsuarioDAOImpl.class.getPackage())
            .addPackages(true, UsuarioWebService.class.getPackage())
            .addAsResource("test-persistence.xml", "META-INF/persistence.xml")
            .addAsWebInfResource(EmptyAsset.INSTANCE, "beans.xml")
            .addAsWebInfResource("sun-jaxws.xml")
            .setWebXML("web.xml");
}

/**
 * UsuarioWebServiceService.
 */
private static UsuarioWebServiceService service;

/**
 * Método responsável pela configuração da classe de teste.
 */
@BeforeClass
public static void setup() {
    service = new UsuarioWebServiceService();
}

/**
 * Método responsável por testar webservice de usuários.
 */
@Test
public void testeUsuarioAutenticacao() {
    Usuario usuario = service.getUsuarioWebServicePort().autenticarUsuario("55550001", "senha");

    Assert.assertNotNull(usuario);
}

/**
 * Método responsável por testar método do webservice que retornar o perfil do usuário pelo seu identificador.
 */
@Test
public void testeUsuarioConsultaPerfil() {
    Usuario usuario = service.getUsuarioWebServicePort().consultarUsuario("99202931");

    Assert.assertNotNull(usuario);
}

/**
 * Método responsável por testar o método que retorna uma lista de usuários pelo seu grupo.
 */
@Test
public void testeUsuarioConsultaGrupo() {
    int grupousuarioAdiministrador = 1;
    Usuario[] usuarios = service.getUsuarioWebServicePort().consultarUsuariosPorGrupo(grupousuarioAdiministrador);
    System.out.println(usuarios.length);
    Assert.assertNotNull(usuarios);
}

So that's fine, the test runs, the Web Service is called and gives the answer that I expected. But after each test method runs, the following stacktrace is printed:
