Examples of org.springframework.dao.OptimisticLockingFailureException

org.springframework.dao.OptimisticLockingFailureException
Exception thrown on an optimistic locking violation.
This exception will be thrown either by O/R mapping tools or by custom DAO implementations. Optimistic locking failure is typically not detected by the database itself. @author Rod Johnson @see PessimisticLockingFailureException
