NullPointerException in QueryTranslatorImpl on erroneously typed delete query
-----------------------------------------------------------------------------

                 Key: HHH-7192
                 URL: https://hibernate.onjira.com/browse/HHH-7192
             Project: Hibernate ORM
          Issue Type: Bug
          Components: query-hql
    Affects Versions: 4.1.1, 4.1.0
         Environment: Hibernate 4.1.1 (also affects 4.1.0), Postgresql
            Reporter: Alex Cruise


Calling code:

    val deleteFileQuery = "delete from FileInstanceEntity f where f.uri = 'file:/blah.txt'"
    em.getTransaction.begin()
    val q = em.createQuery(deleteFileQuery, classOf[FileInstanceEntity]) // FYI classOf[Foo] is the Scala equivalent of Java's Foo.class --
                                                                         // and it's the presence of this parameter that causes problems
    q.executeUpdate()
    em.getTransaction.commit()
