* @assertion A generic class declaration introduces a generic class into the
* enclosing library scope. A generic class is a mapping that accepts a list of
* actual type arguments and maps them to a class. Consider a generic class
* declaration [G] named [C] with formal type parameter declarations [X1 extends
* B1,..., Xm extends Bm], and a parameterized type [T] of the form
* [C<T1,..., Tl>].
* ...
* It is a compile-time error if T is not well-bounded.
* @description Checks that compile error is thrown for the case with one type
* argument
