> {{GenericDelegator.findOne}} doesn't handle the cache consistently.
> When it doesn't find anything, it puts {{GenericValue.NULL_VALUE}} in the cache. When trying to read from the cache it uses the {{getFromPrimaryKeyCache}} method, which returns null when {{GenericValue.NULL_VALUE}} was stored in the cache, just like for cache misses. So a not-found value in the cache is treated like a cache miss and the cache isn't actually used.
