---------- 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
