[jboss-user] [JBossCache] - Re: Optimistic DataVersioningException on read-only objects

[hargitt]

Hi,

We are having a similar problem with Optimistic locking in JbossCache 1.4.1.SP1 together with Hibernate 3.2.2 on JBoss 4.0.4.GA. 

Whenever we commit a trasaction, we are seeing a harmless (it seems) warning:
WARN  [TreeCache] status is 3 (not ACTIVE or PREPARING); returning null)

Futher more, when we are updating two or more different objects simultaneously (same class) we get a versioning exception:

If we run everything under one thread, then then error does not occur. 

I am trying to join this experience with forum entry: http://jboss.org/index.html?module=bb&op=viewtopic&t=92818&postdays=0&postorder=asc&start=30 but if I go back to 1.3.0.SP2 I start getting the null pointer exception bug that was fixed in the next release. 

Any Ideas?
