The functionality I've described is not related to the state transfer in particular, but has to do with how optimistic transactions work.
Was there a state transfer in progress anyway? (hard to determine that from the thread dump)

You can always disable write skew check (<locking writeSkewCheck="false"/>) . That would allow the transaction to succeed even if the value has changed in between the read time and commit time. But that's only if your application can live with that, i.e. an application specific decision.
