Suppose this legal scenario (see 5.5.7. Injection point metadata) with SLSB bean Foo and request scoped bean Bar.
Field Foo#injectionPoint is null.
However the question is whether injection of InjectionPoint on SLSB should be possible. I think it may lead to inconsistencies - SLSB should not have any state as it is usually pooled and reused for every invocation.
