Cannot inject spring data JPA repository into EJB bean on WebSphere

Question

I try to integrate CDI spring-data-jpa in Java EE environment.

I created a very simple repository:

public interface SampleRepository extends JpaRepository<Sample, String> {
}

I also added the CDI producer for the EntityManager:

@ApplicationScoped
class EntityManagerProducer {

    @PersistenceContext
    private EntityManager entityManager;

    @Produces
    @RequestScoped
    EntityManager createEntityManager() {
        return entityManager;
    }

}

Then I want to inject this repository to another CDI bean:

@ApplicationScoped
public class SampleService {

    private SampleRepository sampleRepository;

    public SampleService() {
    }

    @Inject
    public SampleService(SampleRepository sampleRepository) {
        this.sampleRepository = sampleRepository;
    }

}

and also into EJB. For JBoss EAP 7.1 application server it works great - the repository is injected correctly for CDI bean or EJB and I can run queries on the database. However, for WebSphere, I am getting the following exception during startup and the application cannot start:

org.jboss.weld.exceptions.DeploymentException: WELD-001408: Unsatisfied dependencies for type SampleRepository with qualifiers @Default at injection point [BackedAnnotatedParameter] Parameter 1 of [BackedAnnotatedConstructor] @Inject public com.sample.ejb.SampleEJB(SampleRepository) at com.sample.ejb.SampleEJB.(SampleEJB.java:0)

I tried with and without annotation @EnableJpaRepository - the same result. — Adam, Jun 06 '19 at 07:51
Where did you place the annotation? How do you know it was read.' — Alexander Petrov, Jun 06 '19 at 07:59
I had to update the comment - it does not work for CDI beans as well - I was injecting the wrong type — Adam, Jun 06 '19 at 13:03
I found that there is a class JpaRepositoryExtension which should create and add the repository beans. The constructor on WAS is called 4 times. However, the method processAnnotatedType which observes ProcessAnnotatedType event is never called. — Adam, Jun 07 '19 at 11:14
