    Description

            in = get(blockToKey(block), byteRangeStart);
            out = new BufferedOutputStream(new FileOutputStream(fileBlock));
            byte[] buf = new byte[bufferSize];
            int numRead;
            while ((numRead = in.read(buf)) >= 0) {
      

      get() may return null.
      The while loop dereferences in without null check.
