Could not instantiate dialect class HibernateException when Database in CC is expanded
--------------------------------------------------------------------------------------

                 Key: JBIDE-8192
                 URL: https://issues.jboss.org/browse/JBIDE-8192
             Project: Tools (JBoss Tools)
          Issue Type: Bug
          Components: Hibernate
    Affects Versions: 3.2.0.CR1
         Environment: JBDS 4.0.0.CR1 H88, Linux 64
            Reporter: Jiri Peterka


For example when creating dynamic web project and hibernate console (for precise steps see JBIDE-8189) when trying to expand HB CC -> Database for the FIRST TIME there  is an HibernateException (see below). After "Rebuild Configuration" everything goes to normal. Exception is not always here but I saw it several times during few days.
