getInputStream()在JDK1.7.0_25上的突然失效

Question

我已经在我的工作中运行了3年的应用程序，但突然它决定失败。我不知道是否涉及网络问题或其他完全不同的问题。

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格式良好(http://www.blah/?something).

响应头：

HTTP 200 No Error
