[JBoss-user] [JBossCache] - TreeCache/Hibernate/JBossAS optimistic locking problem

[floefliep <do-...@jb...>]

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!
