Spring-security-oauth2 2.0.6 - Mocking security doesn't work after update from 2.0.5

I'm using spring-security-oauth2 version 2.0.5.RELEASE to implement oauth2 in my project. Since I need to return different HTTP response codes based on user's status in the system I need to use my own WebResponseExceptionTranslator in TokenEndpoint. Version 2.0.5 does not allow to configure spring security to use own exception translators but it is possible in the newest version - 2.0.9 RELEASE.

But since version 2.0.6 and newer my unit tests aren't working. I'm using spring-security-test 4.0.3 RELEASE version to mock calls to controller as follow:

@SpringApplicationConfiguration(classes = {AuthorizationServer.class, WebSecurityConfig.class, AuthorizationServerConfig.class, SpringSecurityConfiguration.class})
@WebAppConfiguration
@TestExecutionListeners({DependencyInjectionTestExecutionListener.class})
@RunWith(SpringJUnit4ClassRunner.class)
public class SecurityTest {

@Autowired
private WebApplicationContext wac;

@Autowired
private FilterChainProxy filterChainProxy;

private MockMvc mockMvc;

@Before
public void setUp() {
    mockMvc = webAppContextSetup(wac)
            .addFilters(filterChainProxy)
            .build();
}

@Test
public void allowPatientsToAccessSecureData() throws Exception {
    mockMvc.perform(get(AUTHORIZATION_SERVER + "/user").with(user("user").roles(PATIENT.toString())).secure(true))
            .andExpect(status().isOk());
}
}

But I get response Access is denied - logs are saying that user is anonymous. Is there any solution to get my test working again? It looks as if something has changed with the filter-chain processing.

When I deploy the application security does work, so it's just MockMvc problem.
