Method call x.m(..., v, ...) where v can be null and the corresponding parameter in method m is not annotated with @Nullable

Example:

class C {
  void m(C x) {
    String s = x.toString()
  }

  void test(@Nullable C x) {
    m(x);
  }
}

Action: The preferred action is to ensure that a null value is never passed to the method, by changing the code or changing annotations. If this cannot be done, add a @Nullable annotation to the relevant parameter in the method declaration. This annotation might trigger more warnings in the implementation of method m, as that code must now deal with null values.
