made me think.  the reason is _probably_ so that `class B extends A` would produce a different `hashCode`, but then `A.hashCode` should include not the class instance, but the `getClass()`:


class A {
  public int hashCode() {
    return Objects.hash(getClass(), ...);
  }
}

class B extends A {
  // B.hashCode() produces a value different from A.hashCode()
}
