Hello,

Here an extract of code where the original MappingException is lost.

It is a pity because the original exception has more information to identify the cause of the error.
Indeed, I was obliged to use the debugger to understand my error.

org.hibernate.cfg.annotations.EntityBinder
line 220 :
catch (MappingException me) {
throw new AnnotationException( "Use of the same entity name twice: " + name );
}

Is it possible to replace with
throw new AnnotationException( "Use of the same entity name twice: " + name, me);


thank you and cheer for your work on Hibernate

your error was that you used the same entity name twice, and the name is given to the message.
What additional information was useful?

In fact, the MappingException has a more precise message (with the package name) :

the AnnotationException message :
org.hibernate.AnnotationException: Use of the same entity name twice: Auteur

the MappingException message :
org.hibernate.DuplicateMappingException: duplicate import: Auteur refers to both fr.xavier.pluton.entity.Auteur and fr.xavier.pluton.domain.Auteur (try using auto-import="false")
