>             Project: Hibernate3
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 3.1.2
>         Environment: hibernate 3.1.2 against sysbase 12.5.2 using jconn3 jdbc driver

> I have a POJO which has a column 
> protected Case data;
>   @Type ( type="serializable" )
>   @Basic( fetch=FetchType.EAGER )
>   public Case getData ()
>   {
>     return data;
>   }
>   public void setData (Case data)
>   {
>     this.data = data;
>   }
> I am iterating over every element in the corresponding database table. 
>     Session session = HibernateUtil.currentSession();
>     SQLQuery query = session.createSQLQuery( "select case_id from wf_case" );
>     query.addScalar( "case_id", Hibernate.LONG );
>     List<Long> caseList = query.list();
>     for ( Long caseId : caseList )
>     {
>          WfCase wfCase = (WfCase)session.load( WfCase.class, caseId );
>          if ( wfCase.getData() == null )
>          {
>             System.out.println( "IS  null: " + caseId );
>          }
>          session.evict( wfCase );
>    }
> when I run this, after running through 1500 or 2000 (this number changes between runs), I start getting null returns from wfCase.getData(). After that point, it _always_ returns null. If I call session.evict( wfCase ) on an wfCase which returned null, I get the following exception.

> Now, if I change the session.load to session.get, it runs through without any problems. I thought maybe the second level cache provider was to blame, but I switched to using         <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property> in my cfg file, and I still had the same problem.
> Note, I had the same problem when I wasn't using a serializable type, but was rather just mapping it to a byte[].
