@PreAuthorize не работает с prePostEnabled = true

Question

Используя @EnableGlobalMethodSecurity(prePostEnabled = true) кажется, что

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
}

@PreAuthorized не имеет никакого эффекта:

@PreAuthorize("permitAll()")
@RequestMapping(value = "/users/change-email", method = RequestMethod.GET)
public void changeEmail() {
    // ..
}

Я также переместил аннотацию на сервисный уровень с тем же результатом:

@PreAuthorize("permitAll()")
@Transactional
public void changeEmail(HttpServletResponse response, String token) throws IOException {
     // ..
}

Не понятно, почему - какие идеи?

Вот как я настраиваю ResourceServerConfigurerAdapter:

@Configuration
@EnableResourceServer
public class ResourceServer extends ResourceServerConfigurerAdapter {

    @Override
    public void configure(HttpSecurity http) throws Exception {

        http
                .exceptionHandling()
                    .authenticationEntryPoint(new AuthFailureHandler())
                .and()
                .authorizeRequests()
                    .anyRequest()
                    .authenticated();
    }
}

На данный момент я получаю AccessDeniedException:
