Spec about type variables:
The type parameters of a generic declaration G are in scope in the bounds of all of the type parameters of G. The type parameters of a generic class declaration G are also in scope in the extends and implements clauses of G (if these exist) and in the body of G. However, a type parameter is considered to be a malformed type when referenced by a static member.

Spec about "new":
Let e be a new expression of the form new T.id(a1, .., an, xn+1: an+1, …, xn+k: an+k) or the form new T(a1, .., an, xn+1: an+1, …, xn+k: an+k). It is a static warning if T is not a class accessible in the current scope, optionally followed by type arguments.

So, these tests are not negative, they don't produce compile-time error.
