[cdi-dev] Injection with heritage and CDI

[Martin Kouba]

Hi all,

I think Romain's workaround would not work for the second injection 
point, i.e. for @Inject @FerrariQualifier Car ferrari because 
@Typed(SportCar.class) DefaultSportCar would remove the Car from the 
bean types of DefaultSportCar.

I agree that it looks like an incorrect usage of qualifiers though.
