[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-6829) PooledLoOptimizer.generate() should be synchronized

PooledLoOptimizer.generate() should be synchronized --------------------------------------------------- Key: HHH-6829 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6829 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.6.8 Reporter: Manuel Dominguez Sarmiento Priority: Critical Original Estimate: 0.25h Remaining Estimate: 0.25h We recently switched to this ID generation optimizer in our highly concurrent production platform, and began getting random id / PK collision errors very often. Checking the code, it's pretty obvious that the problem lies with generate() not being synchronized. All other optimizers (PooledOptimizer, LegacyHiLoAlgorithmOptimizer, HiLoOptimizer, etc.) are synchronized - PooledLoOptimizer should be as well.
