Emmanuel Bernard reopened ANN-382:
----------------------------------


Sorry I was too quick on this one. I've added more test cases to test it.
Can you guys have a second try, it should work now (update Hibernate core too).

> As described in hibernate forum (http://forum.hibernate.org/viewtopic.php?t=960763) and discussed with Emmanuel, I encounter a strange behaviour with annotations depending of my package's names.
> Supposing hibernate load classes by package alphabetical order; if it get the "parent" class first all works fine, if it get the "child" class first, it raise an exception ! 
> Here is a subset of my classes, cleaned of getters, setters and all unrelated things, then followed by the exception stack :

> Indeed, depending on the package names I get or not an excpetion !
> It doesn't work with the package fr.ifis.entity.project but if I rename the package in fr.ifis.entity.aproject and then move it "before" the field.card package, all works fine.
> In order to facilitate the identification of the problem, I also include as attachement the eclipse project of this problem repport.
> In order to keep reasonable the size of the attachement, I did not included the libraries nor the configuration files for launch ejb3-embedded. Thoses files are issued from the project simple-deployment included in JBoss EJB 3.0 RC8-FD. The only change i've done was to specify in embedded-jboss-beans.xml the properties of my database.
