native SQL queries in hibernate don't work when using aliases to differentiate columns that have the same name
--------------------------------------------------------------------------------------------------------------

                 Key: EJB-397
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-397
             Project: Hibernate Entity Manager
          Issue Type: Bug
          Components: EntityManager
    Affects Versions: 3.3.2.GA
         Environment: jboss 4.2.2, mysql 5
            Reporter: Alex McCarrier


Basically same as HHH-2094, if you do something like this:

select 
  oldForm.data as oldData
  newForm.data as newData
from 
  form oldForm,
join form newForm on oldForm.replaced_by_id = newForm.id

then use entityManager.createNativeQuery(sql).getResultList()

it will end up with an error that says column named oldData does not exist.  If you take out the aliases, then it will just return the first value for "data" for every column.  If you run this through straight JDBC with the alias,  it works as expected.
