Ola,
Atualmente tenho uma aplicacao utilizando o hibernate 3.2 que recentemente estou migrando o mapeamento para Annotations, no geral tudo funciono bem nessa migracao, o unico problema eh que estou recebendo exception abaixo nos meus testes unitários
Detalhe eh que ao simplesmente deixar trocar o hibernate.cfg.xml do mapeamento da classe para hbm o problema some
Segue execpition:
