    Description

      We have a cache of lucene values in JiraLuceneFieldCache. Apparently this is not of much use, and it simply takes up memory (~280Mb of ~700 in a recent dump) - although it's a WeakHashMap so this memory would be reclaimed if necessary.

      So we should disable this cache. This can be done simply be commenting out line 157:

                      cache.put(reader, readerCache);
