> {{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.
