Test case:

  public class A {
    int foo() {
      int r = 42; // extract this line
      return r;
    }

    public static void main(String[] args) {
      System.out.println(new B().foo());
    }
  }

  class B extends A {
    public int m() {
      return 23;
    }
  }

This program prints 42. Extracting the indicated line into a new method m yields the following program, which prints 23:

  public class A {
    int foo() {
      int r = m();
      return r;
    }

    public int m() {
      int r = 42;
      return r;
    }

    public static void main(String[] args) {
      System.out.println(new B().foo());
    }
  }

  class B extends A {
    public int m() {
      return 23;
    }
  }

The problem is that the extracted method is overridden in B, so the extracted call m() resolves to B.m instead of the extracted method A.m on objects of class B.
