--------------------------------------------------------------------

                 Key: ISPN-692
                 URL: https://jira.jboss.org/browse/ISPN-692
             Project: Infinispan
          Issue Type: Bug
          Components: Lucene Directory
    Affects Versions: 4.2.0.ALPHA2, 4.1.0.Final
            Reporter: Sanne Grinovero
            Assignee: Sanne Grinovero
            Priority: Minor
             Fix For: 4.2.0.BETA1, 4.2.0.Final, 5.0.0.BETA1, 5.0.0.Final


org.infinispan.lucene.InfinispanIndexOutput.getChunkById(AdvancedCache, FileCacheKey, int, int, FileMetadata)
is performing a get() operation for buffers even when it can know from the filesize that such an element will not be found. This is significantly slow when a CacheStore is used, as the cache won't have the value for sure and so it will attempt to load from the store.
