Provide more information in TypeMismatchException message
---------------------------------------------------------

                 Key: HHH-3247
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3247
             Project: Hibernate3
          Issue Type: Improvement
          Components: core
    Affects Versions: 3.2.6
            Reporter: Szczepan Kuzniarz


When DefaultLoadEventListener throws TypeMismatchException it provides information about expected and actual id types:

"Provided id of the wrong type. Expected: " + idClass + ", got " + event.getEntityId().getClass()

but it says nothing about the offending class. It is not always the class which is loaded by client (it may be one of associated classes) and sometimes it's not easy to track it down. It would be nice if DefaultLoadEventListener would report something like this:

"Provided id of the wrong type for class " + persister.getEntityName() + ". Expected: " + idClass + ", got " + event.getEntityId().getClass()
