| * The name of the class is also set to C. Iff the class is prefixed by the |
| * built-in identifier abstract, the class being defined is an abstract class. |
| * @description Checks that class C is not abstract (can be instantiated by |
| * new) if there are no abstract identifier but S in S with M is abstract. Test |
