“Move method refactoring” causes the method call relationship to change

[assdfsdafasfa]

Select the m() method in class C, select the move method refactoring, move it to class B, before refactoring, the f() method calls the m() method of class A, after refactoring, the f() method calls the m() method of class B。

Code before refactoring:

class A {
    void m(Object m) {
        System.out.println("A");
    }
}

class B extends A {
    void k(String m) {
        System.out.println("B");
    }

    void f() {
        m("1");
    }
}

class C {
    B b;
    // move m() to class B
    void m(String m) {
        System.out.println("B");
    }
}

Code after refactoring:

class A {
    void m(Object m) {
        System.out.println("A");
    }
}

class B extends A {
    void k(String m) {
        System.out.println("B");
    }

    void f() {
        m("1");
    }

    // move m() to class B
    void m(String m) {
        System.out.println("B");
    }
}

class C {
    B b;
}

Expected result (correct result):Give an error prompt before executing the refactoring
