``` TransactionalIndexedCollection cache = new TransactionalIndexedCollection(Car.class); cache.addIndex(UniqueIndex.onAttribute(Car.CAR_ID)); cache.add(new Car(1, "Ferrari")); cache.update(Collections.singletonList(new Car(1, "Ferrari")), Collections.singletonList(new Car(1, "Mercedes"))); ``` I expected this to succeed since I am basically trying to update CAR_ID...
