If user copied hotfixed ambari-server.jar to /usr/lib/ambari-server and didn't remove the hotfix, the upgrade will fails with error:

Internal Exception: Exception [EclipseLink-7250] (Eclipse Persistence Services - 2.5.2.v20140319-9ad6abd): org.eclipse.persistence.exceptions.ValidationException

As a workaround, user needs to restore all the database and configuration, remove all the hotfix and run "ambari-server upgrade" again.
