Hi,

The stack trace is weird, it shows an interruption during logging.  Doesn't make a lot of sense.

Regarding your architecture, it does make sense to some degree, although you are still sharing network resources for actual replication (bandwidth), etc.  So you may be over-engineering things a bit, I would have started with just 2 caches (a replicated one and a local one) until you know for sure that there is contention on shared resources.

When using pessimistic locking, locks are per-node so there won't be contention for different entities, as long as they are spread well across the tree structure.

Also, I have just tagged 2.2.1.GA and this should be released today - this has some serialization-related performance enhancements that you may find interesting, as well as a faster JGroups library.

Also, I'd like to add, have you tried 3.0.0.CR1 with MVCC?  It is significantly faster and conceptually more stable than either pessimistic or optimistic locking.
