Regresion! @SequenceGenerator with allocationSize=1 fails Other allocationSizes appear to be decremented by 1
-------------------------------------------------------------------------------------------------------------

                 Key: HHH-5230
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5230
             Project: Hibernate Core
          Issue Type: Bug
          Components: annotations, core
    Affects Versions: 3.5.2
            Reporter: Mike Youngstrom


When I attempt to upgrade to 3.5.2 I get an error on startup. If I change my allocationSize to 2 then it starts up fine but debugging into LegacyHiLoAlgorithmOptimizer it appears to be using a value of 1.
