Grails createCriteria how to use two inLists()

Question

I have a domain class People, which has multiple cars and houses:

def People {
    SortedSet<Car> cars = new TreeSet<Car>()
    SortedSet<House> houses = new TreeSet<House>()
}

def Car {
    Long id
}

def House {
    Long id
}

In grails, I would like to find people who have car with id = 1, and house with id = 1.

How do I achieve this efficiently? I have tried this but it doesn't work:

People.withCriteria {
    cars {
        inList('id', 1L)
    }
    houses {
        inList('id', 1L)
    }
}

Neither does this as it return multiple similar objects:

People.withCriteria {
    createAlias('cars', c)
    createAlias('houses', h)

    inList('c.id', 1L)
    inList('h.id', 1L)
}

Will anyone lend a hand here? Thanks!
