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!
