> The commit logic tries to roll back changes by reversing the update operations and applying them using ds.createOrUpdate().
> However, when the operations that needs to be undone is a "create", the generated Update will only contain removal of properties, but no setting of "_id". If, at this point, the document does not exist in the persistence, a new empty document will be created,
> It appears that this problem can be avoided by using findAndUpdate() instead of createOrUpdate().
