У меня есть приложение, которое я хотел бы проверить на предмет возможных проблем, связанных с Hibernate и / или сохранением.

What other problems? How do I reproduce them (literally)? And how do you recover from them?

To make it clear: I'm talking about multi-threaded cluster environment (the most complex one).

Мой один:

org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect)

Воспроизводить:

Load the object. UPDATE using HQL. Try to update (save) the loaded object.

Обработка: не уверен ...
