    Person personA = new Person("John Doe", 25);
    Person personB = new Person("Jane Doe", 21);
    Person cloneB = new Person("Jane Doe", 21);
    CountListener listener = new CountListener();
    ObjectProperty<Person> personProperty = new ObjectValueProperty<>(personA);
    personProperty.addListener(listener);
    assertThat(listener.getCount()).isEqualTo(0);
    personProperty.set(personB);
    assertThat(listener.getCount()).isEqualTo(1);
    personProperty.set(cloneB);
    assertThat(listener.getCount()).isEqualTo(1);
}
