我正在使用 Hibernate 4.1.0.Final、JPA 2.0、JUnit 4.8.1 和 H2 内存数据库。我有这个 JPA 查询...

@Override
public List<Organization> findByOrgTypesCountryAndState(final List<OrganizationType> organizationTypes,
                                                        final String countryId,
                                                        final String stateId)
{
    final CriteriaBuilder builder = entityManager.getCriteriaBuilder();
    final CriteriaQuery<Organization> criteria = builder.createQuery(Organization.class);
    final Root<Organization> org = criteria.from(Organization.class);
    criteria.select(org);
    criteria.where(builder.and(
                       org.get("organizationType").in(organizationTypes),
                       builder.equal(org.get("state").get("id"), stateId),
                       builder.equal(org.get("country").get("id"), countryId)));
    return entityManager.createQuery(criteria).getResultList();
}

当 java.util.List、organizationTypes 为空时，上述查询将终止，并出现以下异常。我应该使用另一种谓词来解释这种情况吗？ 

org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected end of subtree [select generatedAlias0 from org.mainco.subco.organization.domain.Organization as generatedAlias0 where ( generatedAlias0.organizationType in () ) and ( generatedAlias0.state.id=:param0 ) and ( generatedAlias0.country.id=:param1 )]" type="java.lang.IllegalArgumentException">java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected end of subtree [select generatedAlias0 from org.mainco.subco.organization.domain.Organization as generatedAlias0 where ( generatedAlias0.organizationType in () ) and ( generatedAlias0.state.id=:param0 ) and ( generatedAlias0.country.id=:param1 )]
