JLS3 15.8.2 forbids the type named in the class literal expression from being a parameterized type.
And the grammar in 18.1 disallows (where X and Y are some concrete types) constructs of the form
Outer<X>.class, Outer<X>.Inner.class, Outer.Inner<X>.class, Outer<X>.Inner<Y>.class etc.
Corollary wise, we should resolve the type of the class literal expression to be a raw type as
class literals exist only for the raw underlying type.
