[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-5032) Setting LockModeType.OPTIMISTIC_FORCE_INCREMENT defaults to only OPTIMISTIC

Setting LockModeType.OPTIMISTIC_FORCE_INCREMENT defaults to only OPTIMISTIC --------------------------------------------------------------------------- Key: HHH-5032 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5032 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.5.0-CR-2, 3.5.1 Environment: Hibernate Core 3.5.0-CR-2, Hibernate Validator 4.1 Snapshot, Spring 3.0.1, JPA2 Reporter: Carlos Vara Assignee: Scott Marlow Fix For: 3.5.2, 3.6 Attachments: hhh5032-2.patch, hhh5032.patch, optimisticlocking.tar.gz Using EntityManager.lock(entity, LockModeType.OPTIMISTIC_FORCE_INCREMENT) doesn't change lock type, and version doesn't get updated on transaction commit. The following code: System.out.println("PRE lock mode: " + this.entityManager.getLockMode(an)); this.entityManager.lock(an, LockModeType.OPTIMISTIC_FORCE_INCREMENT); System.out.println("POST lock mode: " + this.entityManager.getLockMode(an)); Outputs: PRE lock mode: OPTIMISTIC POST lock mode: OPTIMISTIC Debugging AbstractLockUpgradeEventListener.upgradeLock, the reason is it doesn't upgrade it because previous lock mode is "READ" (whose level is 5), and OPTIMISTIC_FORCE_INCREMENT has level 4, so it doesn't trigger the update. I'm not sure about Hibernate's LockMode, but I think that OPTIMISTIC_FORCE_INCREMENT is a bit more restrictive than just OPTIMISTIC, so the locking type should be upgraded.
