I get the error below (at CMT commit time) when using the non-clustered combo \
TreeCache 1.4.0cr2 / Hibernate 3.2.0cr2 / JBoss 4.0.4GA. When I switch to pessimistic \
locking (replace OptimisticTreeCacheProvider with TreeCacheProvider and \
NodeLockingScheme OPTIMISTIC by PESSIMISTIC), it all works without faults.

While debugging through the JBoss code, it seems that realNode.getVersion() at line \
124 in OptimisticValidatorInterceptor.simpleValidate() is null.

Any ideas? Tnx!
