ProblemAuthenticationEntryPoint in spring-boot app

Integrating the ProblemAuthenticationEntryPoint as described in the README leads to the following exception on starting a spring-boot application:

***************************
APPLICATION FAILED TO START
***************************

Description:

Field resolver in org.zalando.problem.spring.web.advice.security.ProblemAuthenticationEntryPoint required a single bean, but 2 were found:
        - errorAttributes: defined by method 'errorAttributes' in class path resource [org/springframework/boot/autoconfigure/web/ErrorMvcAutoConfiguration.class]
        - handlerExceptionResolver: defined by method 'handlerExceptionResolver' in class path resource [org/springframework/boot/autoconfigure/web/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]


Action:

Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed

Which one to pick?

[kakawait]

Using a qualifier is always more expressive and more importantly it’s safe against refactorings, especially accidental ones.

Maybe, but if we really want to be safe we should create kind of integration test against small Spring boot app
