> 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.
