Generic and checked collections

Question

Yet another problem.
This afternoon, i try to use checked collection
(Collections.checkedMap(...)) with a parameterized type
of parametrized types.
Examples :
Map<String,Integer> map=Collections.checkedMap(
new HashMap<String,Integer>(),String.class,Integer.class)
this example works but
Map<Class<?>,EnumSet<MyEnum>> map=Collections.checkedMap(
new HashMap<Class<?>,EnumSet<MyEnum>>(),Class<?>.class,EnumSet<MyEnum>.class)
because the grammar does not permit to declare "parameterized class dot class",
like Class<?>.class so i can correctly types arguments of checkedMap.
so i have to use an ugly workaroud using raw types :
Map<Class<?>,EnumSet<MyEnum>> checkedMap=
(Map<Class<?>,EnumSet<MyEnum>>)(Map)Collections.checkedMap(
(Map<Class,EnumSet>)(Map)map,Class.class,EnumSet.class);
I my mind :
A.class is typed Class<A>
A<?>.class is typed Class<A<?>>,
the later notation is mandatory because lot of methods like checkedMap()
use this pattern :
m(T t, Class<T> clazz)

Answer 1

A<B>.class, If this would be allowed, IMHO this should be equivalent to
(Class<A<B>>) A.class
But the latter does not compile: incompatible types
Why? I expected an unchecked cast warning.
