Why does Hibernate generate a CROSS JOIN for an implicit join of a @ManyToOne association?

I’ve noticed one of the base classes (DAOImpl) in the DAO hierarchy has many final methods which makes it unfriendly to mock (I’m excluding byte code manipulators like Powermock as a solution). I’m currently using the MockConnection and MockDataProvider pattern to
