我已经在工作中运行了一个应用程序 3 年时间,但突然之间它决定失败。我无法弄清楚是否涉及网络问题或完全不同的东西。

堆栈跟踪:

java.lang.NullPointerException
    at sun.net.www.protocol.http.NegotiateAuthentication.isSupported(NegotiateAuthentication.java:99)
    at sun.net.www.protocol.http.AuthenticationHeader.parse(AuthenticationHeader.java:180)
    at sun.net.www.protocol.http.AuthenticationHeader.<init>(AuthenticationHeader.java:126)
    at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1374)
    at domain.ActivationSMSReceiverMain.processLogFromUrl(SMSSys.java:327)
    at domain.ActivationSMSReceiverMain.<init>(SMSSys.java:45)
    at domain.ActivationSMSReceiverMain.main(SMSSys.java:477)

代码示例:

URL url = new URL(uri);
HttpURLConnection uc = (HttpURLConnection) url.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(uc.getInputStream()));

我已确保uri格式正确(http://www.blah/?something)。

响应头:

HTTP 200 No Error

问题是代理服务器出现故障,因此问题自行解决。
