> 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.
