随机获取com.sun.jersey.api.client.ClientHandlerException：java.io.IOException：Stream closed error

Question

我不确定我的代码会在哪里导致错误：

com.sun.jersey.api.client.ClientHandlerException: java.io.IOException: Stream closed.
at com.sun.jersey.api.client.ClientResponse.bufferEntity(ClientResponse.java:583)
at moveit.PipelineMetadata.checkPipelineRunStatus(PipelineMetadata.java:1013)

它失败的代码行是：

ObjectMapper mapper = new ObjectMapper();

在代码中的这一部分：

ClientResponse response = webServiceConnect(siteLine) + "/status?rev=0").accept("application/json")
                        .get(ClientResponse.class);

        // Pipeline not found
        if (response.getStatus() == 500) {

            throw new NoPipelineFoundException("Pipeline not found : " + response.getStatus());
        }

        // Other error
        if (response.getStatus() != 200 && response.getStatus() != 500) {
            throw new RuntimeException("Failed : HTTP error code : " + response.getStatus());
        }

        response.bufferEntity();

        ObjectMapper mapper = new ObjectMapper();
        mapper.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false);
        mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
        pipelineStatus = mapper.readValue(response.getEntity(String.class), PipelineStatus.class);

        pipelineRunStatus = pipelineStatus.status;
        return pipelineRunStatus;

我的代码是否有问题，或者这可能是网络服务器的超时问题？
