> ReplicatedHashMap does not correctly handle state transfer during a merge, leaving members with inconsistent map entries.
> Specifically, on receipt of a MergeView no attempt is made to reconcile the state of all members. Each member retains the entries it had while partitioned, though all members will correctly apply subsequent mutations.
> I've attached a unit test that demonstrates the bug and also a patch that corrects the behavior (specifically, by calling getState() on the coordinator of each subview on receipt of a MergeView).
