If I have @Version in my entity, but I don't use LockModeTypes in transaction, what would be modified beyond of update the column? @Version alone makes some difference?

[admin]

As per Section 3.4.4.1

If a versioned object is otherwise updated or removed, then the implementation must ensure that the requirements of LockModeType.OPTIMISTIC_FORCE_INCREMENT are met, even if no explicit
call to EntityManager.lock was made.

So, even if you don't use locking, the semantics will be the same if you have @Version.

HTH,
