Предотвратить откат внутренней транзакции от внешней транзакции

У меня несколько сложная транзакция, которая создает или не создает много разных типов объектов. Если он не смог создать один из этих объектов из-за ошибки проверки, я хотел бы просто поймать ConstraintValidationError и перейти (чтобы любые другие сущности, созданные в одной транзакции, успешно сохранялись).

Я могу сделать это успешно, но ошибка проверки по-прежнему отмечает всю мою транзакцию для отката, чего я не хочу.

Я попытался изменить единственный метод проверки, который вызывает у ConstraintValidationError следующее:

@Transactional(propagation = Propagation.NOT_SUPPORTED)

чтобы заставить новую транзакцию думать, что она будет отмечать только эту новую, внутреннюю транзакцию для отката, но это, похоже, не так.

Вызывающий класс помечен:

@Transactional(noRollbackFor=ConstraintViolationException.class)

но это не помогает, если ConstraintViolationException находится в вызываемом методе, и я не хочу добавлять его к вызываемому методу.

Каков правильный способ сделать что-то подобное?

(Дайте мне знать, если требуется код - пример несколько сложный.)

EDIT (5/26/14):

Когда я пытаюсь

progration = Propagation.REQUIRES_NEW

Я не вижу изменений в результате. Этот конкретный журнал исходит из теста, целенаправленно пытающегося сохранить объект сущности "department" с нулевым описанием, что было бы неверным:

Если я не уверен, правильно ли я это читаю, я вижу нулевую структуру подразделения, а затем информацию, которую он откатывает, но можно было бы подумать, что это указывает на то, почему он решил откат.
