Suppose this legal scenario (see 5.5.7. Injection point metadata) with SLSB bean Foo and request scoped bean Bar.

@Stateless
public class Foo {
 @Inject
 InjectionPoint injectionPoint;
}

@RequestScoped
public class Bar {
 @Inject
 Foo foo;
}

Field Foo#injectionPoint is null (no UnsatisfiedResolutionException thrown!).

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.
