My current client does not wish to use the versioning feature of JPA/Hibernate at this time. They do not see the need for it. I could argue differently, but that is not my call at this point. So, my question is rather simple. Do I have to do ANYTHING in order to turn off versioning/optimistic locking? I was hoping it would just work out of the box that way. I shoudl also note that it is a goal if possible to NOT reference hibernate in any of my source code (trying to stay provider neutral at this point). I have read something in another post that suggests that it is disabled unless you configure it, however I want to be sure there is not extra comparing going on during each commit (I want to retain control of that). Thank you in advance for any help!
