[jboss-user] [JBossCache] - Re: NPE when using optimistic locking with JbossCache 1.4.0.

[rkrol]

To return on my problem with org.hibernate.cache.OptimisticTreeCache$DataVersionAdapter and org.hibernate.cache.OptimisticTreeCache$NonLockingDataVersion on delete operation...
Everthing is ok if I modify the class org.jboss.cache.interceptors.OptimisticValidatorInterceptor to delete an if statement that generate the DataVersioningException : if(!realNode.getVersion().getClass().equals(workspaceNode.getVersion().getClass())) line 142.

The problem is that Hibernate considers that the DataVersion can change from a type to an other (NonLockingDataVersion to DataVersionAdapter), but it's not the idea on JBC.
So my question : Is it important to have the same type before and after the update of the node ? Does the "newerThan(DataVersion)" method not supposed to manage the different type to be able to compare him to an other kind of DataVersion ?
