private CodecPool(final CompressionCodec codec){
  try {
    boolean supportDirectDecompressor = codec instanceof DirectDecompressionCodec;
    compressorPool = new GenericObjectPool(new BasePoolableObjectFactory() {
      public Object makeObject() throws Exception {
        return codec.createCompressor();
      }
    }, Integer.MAX_VALUE);

    Object com = compressorPool.borrowObject();
    if (com != null) {
      cPools.put(com.getClass(), compressorPool);
      compressorPool.returnObject(com);
    }else{
      logger.warn("Unable to find compressor for codec {}", codec.getClass().getName());
    }

    decompressorPool = new GenericObjectPool(new BasePoolableObjectFactory() {
