> Previous checkins cleaned up some of the odd exception propagation choices (Throwables.propagate is deprecated), there's a little more work on that here. Additionally, the InMemory's InstanceList wasn't previously generically typed, which made some of the code excessively cautious. I added the generic typing and removed the sprinkling of Precondition checks which seems to have been designed to work around not having proper compile-time type checking. Also, it turned out to be unnecessary to track the class in the KVStoreView, which allows for the easy creation of an EMPTY_VIEW singleton.
> Note that we also see an opportunity to simplify the KVStore implementation tests as the verification of the KVStore APIs should be independent of the implementation and the tests should probably be written once and then run against both implementations. However, we decided not to attempt that at this time.
