Upgrading from Hibernate 3.2.5.ga to Hibernate 3.5.6.Final

Below is the summary of the experiment.  After the changes below all unit tests run successfully in all csf components.

1. For compilation:
   • One line in HibernateEvaluationResponseDao.java and in HibernateEvaluationSubjectGroupDao.java has to be changed from:

     new DistinctRootEntityResultTransformer()
     

     and must be changed to

     DistinctRootEntityResultTransformer.INSTANCE
     

2. For running unit tests:
   • The following dependency had to be added to the pom file.

     <dependency>
         <groupId>org.hibernate</groupId>
         <artifactId>hibernate-ehcache</artifactId>
         <version>3.5.6.Final</version>
     </dependency>
     

   • The id sequence generator no longer supports the type String. As a result, the domain object NonSubjectAcademicCredit must extend AbstractDomainLongIdBase instead of AbstractDomainStringIdBase.
     Also, the hbm mapping should be updated accordingly. (Note: The type in the database is NUMBER, so it should have been Long from the beginning!!)
   • Workflow complained about missing classes so the following had to be added to the pom file (Note: it really should be added to the workflow pom file and not common-legacy)

     <dependency>
         <groupId>javassist</groupId>
         <artifactId>javassist</artifactId>
         <version>3.12.1.GA</version>
     </dependency>
