[hibernate-issues] [Hibernate-JIRA] Created: (HHH-7230) Query "select new pakage.Object ..." throws the ClassCastException when the first level pakage is "by"
Query "select new pakage.Object ..." throws the ClassCastException when the
first level pakage is "by"
------------------------------------------------------------------------------------------------------
Key: HHH-7230
URL: https://hibernate.onjira.com/browse/HHH-7230
Project: Hibernate ORM
Issue Type: Bug
Components: query-criteria, query-hql
Environment: hibernate-release-4.1.1.Final, Oracle 11.
Reporter: Anton Bastynets
Priority: Minor
The problem appears, when class is placed in the package with first level "by",
e.g. "by.bntu.shop.domain.dto.ProductDto".
Test method:
public void testExecSearchQuery1() {
EntityManagerFactory emf =
Persistence.createEntityManagerFactory("VideoShopPU");
EntityManager entityManager = emf.createEntityManager();
String queryStr = "SELECT new by.bntu.shop.domain.dto.ProductDto(c.id,
c.price) FROM ProductEntity AS c";
TypedQuery<ProductDto> query = entityManager.createQuery(queryStr,
ProductDto.class); //throws exception!
List<ProductDto> results = query.getResultList();
}
Stack trace:
