NPE at startup with Hibernate 5.4.29 and "version false" domain classes

[alanwilkie-finocomp]

Hibernate has made a change between 5.4.28 and 5.4.29 that adds some convenience methods to the OptimisticLockingStyle enum. Consequently, it expects that the optimistic locking style for each entity is always set to a proper value. GrailsDomainBinder currently only calls setOptimisticLockingStyle if the domain class has a version property.

It's arguable whether it's a GORM issue or a Hibernate issue (it seems a bit rough to make a breaking change to the behaviour in a 0.0.1 release), but it's not too hard to fix in GORM.
