[Hibernate-issues] [Hibernate-JIRA] Commented: (HBX-633) Reverse engineered VERSION columns cause ClassCastException

[Max R. A. (JIRA) <no...@at...>]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HBX-633?page=comments#action_22663 ] 

Max Rydahl Andersen commented on HBX-633:
-----------------------------------------

ok so the problem is that we too blindly select columns named VERSION to be version column. will also have to check that the resulting type is compatible.

until then you can work around it via a custom reveng strategy that just returns false for useColumnForOptimisticLock.
