Issue

• Building a criteria query to execute join fetch for an entity type and its ManyToOne association (e.g. Employee.department -> Department)

• Filtering the query by properties of the joined type (Department)

  final CriteriaBuilder builder = entityManager.getCriteriaBuilder();
  final CriteriaQuery<Employee> criteria = builder.createQuery(Employee.class);
  
  final Root<Employee> root = criteria.from(Employee.class);
  
  // Create the join fetch to instantiate, in memory, the association between Employee, Department and Manager
  final Fetch<Employee, Department> departmentFetch = root.fetch(Employee_.department, JoinType.INNER);
  departmentFetch.fetch(Department_.manager, JoinType.INNER);
  
  // Create a join to get the path to the joined entity's property
  final Join<Employee, Department> departmentJoin = root.join(Employee_.department, JoinType.INNER);
  
  // Filter against a Department property
  criteria.where(builder.equal(departmentJoin.get(Department_.name), "Support"));
  
  // Execute the query
  entityManager.createQuery(criteria).getResultList();
  

• The query execution raises

  org.hibernate.QueryException: query specified join fetching, but the owner of the fetched association was not present in the select list ...
  

• The same query executed without raising an exception prior to EAP 6.3.1
