      If I try to apply @Transactional on a bean through InterceptionFactory like this:

      interface MyService {
    void doSomething() throws Exception;
}

@Produces
@ApplicationScoped
public MyService myService(InterceptionFactory<MyService> interceptionFactory) {
    interceptionFactory.configure().add(new TransactionalLiteral(Transactional.TxType.REQUIRED));
    return interceptionFactory.createInterceptedInstance(() -> System.out.println(TransactionManager.transactionManager().getStatus()));
}

      and call the MyService.doSomething() method somewhere in my application, I can see 0 being printed (which says that there is an active transaction) but I still get the following exception after invocation:

      java.lang.NullPointerException

      The interceptor is trying to find the @Transactional annotation on the AnnotatedType but fails as it has been added via the InterceptionFactory. I know there is no easy solution as long as CDI-468 is not solved but do you think there is a workaround?
