      and the second one is on some kind of replication related request:

      The Environment is a 3 node SOLR Cloud setup running SOLR 5.2.1.

      when looking at the code:

      public synchronized String[] listAll() throws IOException {
          final Set<String> files = new HashSet<>();
          for(String f : cache.listAll()) {
            files.add(f);
          }
          for(String f : in.listAll()) {
            if (!files.add(f)) {
              throw new IllegalStateException("file: " + in + " appears both in delegate and in cache: " +
                                              "cache=" + Arrays.toString(cache.listAll()) + ",delegate=" + Arrays.toString(in.listAll()));
            }
          }
          return files.toArray(new String[files.size()]);
        }
      

      i can see that the exception is thrown because the file exists in both the cache and the file system.
      this however doesn't make sense to me, because a file that is in cache will always be in the file system as well.
