/**
* ShadowPartitionedRegion for replicated region uses this PartitionResolver. In shadowPR for RR, we
* are storing eventID as key into the buckets calculated from "key" of the original events. It
* means unlike to normal scenario, in this case bucket id (in which EventIDs are added as key) is
* different from the bucket id calculated using EventID's hashcode. To not to break the contract of
* key and its bucket id, we are providing an internal resolver which will return a correct bucketId
* when EventID will be used as the key in RR with PArallelGatewaySender
*
* We are assuming here, before calling getRoutingObejct in this Resolver, key of EntryOperation
* i.e. EventID as already been processed by ParallelGatewaySenderImpl#setModifiedEvent where we are
* calculating bucketId from original event's key and storing it in EventID.
