HHH-3608: DB sequence numbers are not unique when using the pooled SequenceStyleGenerator in multiple JVMs with the same DB

Details

    • Bug
    • Resolution: Done
    • Critical
    • 4.3.0.GA_CP10
    • 4.3.0.GA_CP09
    • Hibernate
    • None

    • Hibernate 3.3.2_CP03, Oracle (any version)

    • Hide
      When org.hibernate.id.enhanced.OptimizerFactory.PooledOptimizer was used in multiple JVMs with the same database, there was a risk of duplicate sequenced values being generated. This occurred because a method was invoked twice to initialize two different values (value and hiValue). If another JVM requested a sequence value between these invocations, the sequence related to the second invocation. This issue has been corrected by limiting the double-read to optimizer initialization, when the first read gives Hibernate the initialValue.
