Mark Struberg commented on OWB-568:
-----------------------------------
Digging deeper into this revealed a few other issues. In general I'd like to note that all the Generic Interceptor stuff is highly accademical imo, because only @Dependent beans might be generics at all!
See section 3.1 of the spec:
> 3.1. Managed beans
> ...
> If the managed bean class is a generic type, it must have scope @Dependent.
> If a managed bean with a parameterized bean class declares any scope other than @Dependent,
> the container automatically detects the problem and treats it as a definition error.
Thus it's only possible to decorate @Dependent generic beans which kinda sucks ;)

-----------------------------------
Just to clarify my previous sentence:
@ApplicationScoped
public class Zoo<?> { ..
is illegal, but
@ApplicationScoped
public class ViennaZoo extends Zoo<Vienna> { ..
is fine.

----------------------------------
The patch is against the 1.1.0 tag. It fixes one problem, but another is still remaining.

Arne Limburg commented on OWB-568:
----------------------------------
As you wrote, it's not that academic at all, because beans may implement generic interfaces and generic decorators seem to be valid as of the example in 1.3.7 of the spec.
Your bean ViennaZoo may be decorated by the following decorator
@Decorator
public class CityZooDecorator<C extends City> implements Zoo<C>
@Inject @Delegate
private Zoo<C> delegate;
...
}
But I guess this decorator would not applied to the bean
@ApplicationScoped
public class Parliament implements Zoo<Germany> {
...
}
since germany is not a city.
