             Summary: FileCache getIfPresent doesn't update cache hit/miss counters
                 Key: OAK-6413
                 URL: https://issues.apache.org/jira/browse/OAK-6413
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: blob
    Affects Versions: 1.6.1
            Reporter: Ioan-Cristian Linte
            Priority: Minor


{{FileCache.getIfPresent}} bypasses cache access if key is not in cache and CacheStats for "DataStore-DownloadCache" MBean will always have 100% hit rate even when Blobs will be downloaded from the BlobStore backend by {{AbstractSharedCachingDataStore}} because of the miss in the cache.

I suggest the following change:
{{FileCache.getIfPresent}} to call {{CacheLIRS.getIfPresent}} which will update the cache stats (miss and hit counters).
