http://stackoverflow.com/questions/31776602/illegalargumentexception-occurred-calling-getter-of-id-when-doing-cascading-inse

In short, when I do INSERT in MySQL using session.save(object), I get IllegalArgumentException when calling the getter of target class. I have mapped it all right and I don't know why.
