Hi all, I'm a bit confused with the mentioned lock mode.
*The doc says the following:* *"The entity is locked pessimistically and its version is incremented automatically even if the entity has not changed."* I'm checking this with an H2 DB and the current behavior is the following: - the version attribute is incremented in advance, right after fetching (I'm using EntityManager#find here, but with lock, it should be the same) - the original fetching query contains the SELECT ... FOR UPDATE clause Knowing this, it seems for me that this lock mode involves a DB lock, however the doc doesn't say anything about this, especially whether it's a shared or exclusive lock. I've checked Vlad's article about this. https://vladmihalcea.com/2015/02/16/hibernate-locking-patterns-how-does-pessimistic_force_increment-lock-mode-work/ It says the following: "*The PESSIMISTIC_FORCE_INCREMENT naming might lead you into thinking that you are using a pessimistic locking strategy, while in reality this Lock Mode is just an optimistic locking variation."* So now I'm unsure what this really is. Could you please briefly describe it to me if I missed something? Thanks in advance!
