在java 11上的http响应上调用close时，我得到了以下异常。这曾经适用于java 8。

Caused by: javax.net.ssl.SSLException: closing inbound before receiving peer's close_notify

在下面的代码中调用response.close()时会发生上述异常：

    HttpGet httpRequest = new HttpGet(url);
    CloseableHttpResponse response = null;
    BufferedReader reader = null;
    try {
        response = httpClient.execute(httpRequest);
        reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
        String line = "";
        while((line = reader.readLine()) != null) {
         // do something with the line
        }
    } catch (Exception e) {
        e.printStackTrace();
        throw e;
    } finally {
        if (response != null) {
            response.close();
        }
        if (reader != null) {
            reader.close();
        }
    }

我使用的是httpclient 4.5.3。我在reader.close()上也观察到了同样的错误。

任何帮助都是非常感谢的。

您试图以错误的顺序关闭请求和读取器。在我看来，你最好重新格式化代码，使用try-with-resource块来自动关闭资源，这样你就不会再遇到这种问题：

HttpGet httpRequest = new HttpGet(url);
try (CloseableHttpResponse response = httpClient.execute(httpRequest)) {
    try (BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()))) {
        String line = "";
        while ((line = reader.readLine()) != null) {
            // do something with the line
        }
    }
} catch (Exception e) {
    e.printStackTrace();
    throw e;
}
