> {{AbstractMergedSortedCacheStoreIterator}} uses the wrong cache key
> deserializer in {{peekNextKey}}. This may result in errors or incorrect keys
> returned from {{peekNextKey}} on a {{WindowStoreIterator}} or
> {{SessionStoreIterator}} for a cached window or session store.
> CachingKeyValueStore does not seem to be affected.
