      Test class from /src/test/java:

      public class CoreEntityDaoTest {

    public static class DummyDao/* extends CoreEntityDao<DummyEntity, UUID>*/ {
        public DummyDao(EntityManager entityManager) {
        }

        public void findById(UUID uuid) {
        }

        public DummyEntity save(DummyEntity e) {
            return e;
        }
    }

    @Table(name = "dummy")
    public static class DummyEntity {

    }

    @Inject
    private DummyDao dao;

    static Weld createWeld() {
        Weld weld = new Weld();
        // needed to allow visibility to the main beans, not just the test ones
        weld.property(Weld.ARCHIVE_ISOLATION_SYSTEM_PROPERTY, false);
        return weld;
    }

    @Rule
    public WeldInitiator weld = WeldInitiator.from(createWeld().addBeanClass(DummyDao.class))
                                             .activate(RequestScoped.class)
                                             .inject(this)
                                             .build();

    @Test
    public void testSave() {
    }
}

      This is a simplifed test class that should demonstrate the problem.
      Just run it as a JUnit test.

      Running a test that's using weld-junit4 to initialize the CDI container triggers this exception:

      The test itself is incorrect (I was just trying to add the inner class DummyDao to the CDI context), but I don't think the NPE should be thrown anyway.
      To fix the test, marking the constructor of DummyDao with @Inject and removing the call .addBeanClass(DummyDao.class) is enough.
