> It looks like there is a data race between the state transfer thread and a concurrent transaction in EntryWrappingInterceptor.commitEntryIfNeeded:
> tx: commitContextEntry()
> ST: stateConsumer.isKeyUpdated(k)? false
> tx: stateConsumer.addUpdatedKey(k)
> ST: commitContextEntry()
> We probably need some synchronization here, maybe using EquivalentConcurrentHashMapV8.computeIfAbsent().
