[cdi-dev] Clarification for manually resolving 'Instance'

[Pete Muir]

See section 5.6.2. The built-in Instance - the spec only requires a bean of type Instance<X> not of raw type Instance<>

I'm not sure there is a generalization here (or I don't understand yours). The parameterized type resolution rules are correct, it's just there is no raw type of Instance to resolve.

Should there be? Not sure if it would just be more confusing?

This should work on Weld to.
