ConnectionPoolTimeoutException：超时等待连接池

Question

我有应用程序，不断调用一个API的JSON数据，并很快我看到这个'超时等待连接池'异常，我GOOGLE了周围，发现这是一个连接泄漏引起的内容不会被消耗，所以我更新的代码消耗jsondata后关闭InputStream，但还是得到了那些连接超时异常，这里是我的代码：

InputStream is = ApiUtil.getAsStream(Api.get(bookUrl).param("limit","500").param("bookId", bid).enable(Options.LongRunning), 3); 
List<JsonBook> books = mapper.readValue(is, BOOK_TYPE); 
is.close() 

Api: 
    private JsonHttpClient client; 
    public APIForGet get(String endpoint) { 
    return new APIForGet(this.client, endpoint); 
    } 

ApiUtil: 
    public static InputStream getAsStream(APIForGet get, Iterable<Long>retries) { 
     return get.asStream();  
    } 
APIForGet: 
    private JsonHttpClient client; 
    public InputStream asStream() { 
     return this.client.getAsStream(this.hostname, this.port, this.endpoint, params, optionsArray()); 
    } 

JsonHttpClientImpl: 
    public InputStream getAsStream(Optional<String> host, Optional<Integer> port,String path, Multimap<String, String> param, Options ... options) { 
    HttpResponse reponse; 
    try { 
    response = request.execute(); 
    if (response.isSuccessStatusCode()) { 
     return response.getContent(); 
    } 
    } catch (Exception e) { 
    throw new Exception(); 
    } 
} 

这里的包装逻辑是一种复杂的，但最终我想通过关闭输入流应该工作，任何想法？谢谢！

try { 
    response = request.execute(); 
    if (response.isSuccessStatusCode()) { 
     return response.getContent(); 
    } 
    } catch (Exception e) { 
    throw new Exception(); 
    }finally{ 
     //TODO release conn or abort 
    }
