Zero length value would cause value compressor read nothing and not advance the position of the InputStream

  public static void main(String[] args) throws Exception {
    CompressionContext ctx =
      new CompressionContext(LRUDictionary.class, false, false, true, Compression.Algorithm.GZ);
    ValueCompressor compressor = ctx.getValueCompressor();
    byte[] compressed = compressor.compress(new byte[0], 0, 0);
    System.out.println("compressed length: " + compressed.length);
    ByteArrayInputStream bis = new ByteArrayInputStream(compressed);
    int read = compressor.decompress(bis, compressed.length, new byte[0], 0, 0);
    System.out.println("read length: " + read);
    System.out.println("position: " + (compressed.length - bis.available()));
