      ---------- BEGIN SOURCE ----------
      public interface Call<T extends Exception>
      {
         void run() throws T;
      }


      import java.lang.annotation.Target;

      import static java.lang.annotation.ElementType.TYPE_USE;

      @Target(TYPE_USE)
      public @interface NotNull {
      }


      public class Parent
      {
         public Parent(@NotNull Call initAlgorithm)
         {
         }
      }


      public class Child extends Parent
      {
         public Child()
         {
            super(() -> {});
         }
      }

      ---------- END SOURCE ----------

      CUSTOMER SUBMITTED WORKAROUND :
      Add generic parameters to Call in the Parent constructor.
      Alternatively, do not use TYPE_USE on the annotation.

      FREQUENCY : always
