> If a region configures eviction with overflow to disk then it is possible that a CacheWriter method that calls EntryEvent.getOldValue may see it return null. This happens when the old value for that entry was evicted to disk.
> In the case of a CacheWriter, geode should in this case ask for the old value that is on disk and return it.
