Exception raising : Strange behaviour depending on package names
----------------------------------------------------------------

         Key: ANN-382
         URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN=
-382
     Project: Hibernate Annotations
        Type: Bug

 Environment: Hibernate's annotations packaged in JBoss EJB 3.0 RC8- FD
Microsoft SQL Server 2000
    Reporter: Pierre Four=C3=A8s
 Attachments: BugEJB3.zip

As described in hibernate forum (http://forum.hibernate.org/viewtopic.php?t=
=3D960763) and discussed with Emmanuel, I encounter a strange behaviour wit=
h annotations depending of my package's names.

Supposing hibernate load classes by package alphabetical order; if it get t=
he "parent" class first all works fine, if it get the "child" class first, =
it raise an exception !=20

Here is a subset of my classes, cleaned of getters, setters and all unrelat=
ed things, then followed by the exception stack :=20

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.car=
d 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-bean=
s.xml the properties of my database.

Regards,
Pierre.
