>             Project: Infinispan
>          Issue Type: Feature Request
>    Affects Versions: 5.1.0.FINAL
>            Reporter: Mircea Markus
>            Assignee: Mircea Markus
>            Priority: Critical
>             Fix For: 5.2.0.CR1, 5.2.0.Final
>
>
> The StaleTransactionCleanupService uses explicit locking in order to unlock the keys for which it is no longer owner as the result of a rebalance.
> This works for pessimistic caches but doesn't work for the optimistic ones, as the LockCommand causes an exception when processed by the OptimisticLockingInterceptor
