For the record:
if you write a @RequestScoped bean without a default ct, then you cannot use it. Not via @Inject, nor via @EJB nor via BeanManager#getReference, Provider or Instance... It would just trash at runtime.
Imo this is a clear programming error from the user.

Theoretically you can use a contextual instance obtained by Context.get(). But yes, it does not make much sense.

Please note that the spec defines in which cases the container must detect a problem - but it doesn't say that other cases must work. In OWB we just detect those cases as bugs as well. This is of course not required, but also not forbidden.

Yes, that's why we fixed the test
