JPA Subquery does not work in Criteria API

Question

I'm learning Criteria API. I am trying to rewrite all my JPQL queries to Criteria API queries.

I use sakila database (http://dev.mysql.com/doc/sakila/en/), MySQL database and HibernatePersistence JPA provider.

I have got stuck in rewriting following query:

SELECT c FROM Customer c 
JOIN c.addressId a 
JOIN a.cityId ct 
WHERE ct.countryId IN (SELECT co FROM Country co WHERE co.country = 'Germany')

It works fine, but the same in Criteria API doesn't work:

CriteriaBuilder cb = em.getCriteriaBuilder();
CriteriaQuery<Customer> c = cb.createQuery(Customer.class);     
Root<Customer> cust = c.from(Customer.class);
Join<Customer, Address> address = cust.join(Customer_.addressId);
Join<Address, City> city = address.join(Address_.cityId);

Subquery<Country> sq = c.subquery(Country.class);
Root<Country> country = sq.from(Country.class);
sq.select(country).where(cb.equal(country.get(Country_.country), "Germany"));
c.where(cb.in(city.get(City_.countryId)).value(country));

I have got the following exception:

The query which is produced by Hibernate looks like:

select 
customer0_.customer_id as customer1_5_, 
customer0_.active as active2_5_, 
customer0_.address_id as address_8_5_, 
customer0_.create_date as create_d3_5_, 
customer0_.email as email4_5_, 
customer0_.first_name as first_na5_5_, 
customer0_.last_name as last_nam6_5_, 
customer0_.last_update as last_upd7_5_, 
customer0_.store_id as store_id9_5_ 

from customer customer0_ 
inner join address address1_ on customer0_.address_id=address1_.address_id 
inner join city city2_ on address1_.city_id=city2_.city_id 

where city2_.country_id=generatedAlias3;

Thank you in advance.
