PersistentClass classname is not revealed in MappingException
-------------------------------------------------------------

                 Key: HHH-3170
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3170
             Project: Hibernate3
          Issue Type: Improvement
    Affects Versions: 3.2.x, 3.3
            Reporter: Paul Benedict


A typical exception from bad configuration is:
Caused by: org.hibernate.MappingException: Could not determine type for: java.util.Map, for columns: [org.hibernate.mapping.Column(name)]

Recommendation:
The "org.hibernate.cfg.Configuration" class should catch the exception and add the name of the offending PersistentClass. The class is held by the iterator. 

Line 1100 improvement:
private void validate() throws MappingException {
  Iterator iter = classes.values().iterator();
  while ( iter.hasNext() ) {
  PersistentClass pc = (PersistentClass) iter.next();
  try {
    pc.validate( mapping );
  } catch(MappingException e) {
    throw new MappingException(pc.getClassName(), e);
  }
  ....
}

Otherwise, I find it incredibly difficult to find the offending class without a step debugger.
