Question

我继承了一些代码，不知道它正在尝试做什么（我评论了我认为它在做什么），原来的编码员多年前就离开了我的组织......我希望这里的伟大社区能够至少指出我的意思关于这段代码可能尝试做什么的一些方向，以及我可以在哪里开始寻找解决方案...

Java代码

//Read java.security file from JDK and create a Security provider from it
PropertyFileReader reader = new PropertyFileReader();
Security.addProvider(new IBMJSSEProvider());
Security.setProperty("ssl.SocketFactory.provider",
"com.ibm.jsse2.SSLSocketFactoryImpl");
System.getProperties().putAll(
reader.readProperties("security.properties"));

//Set some authentication stuff
Authenticator.setDefault(new PasswordAuthentication("User", "Password"));

// get url to servlet (note, actual application has valid url)
url = new URL("Connection URL");

// Set out HTTP URL connection
httpURLConnection = (HttpURLConnection) url.openConnection();
httpURLConnection.setRequestProperty("Authorization", "Basic ");
httpURLConnection.setDoInput(true);
httpURLConnection.setDoOutput(true);
httpURLConnection.setUseCaches(false);
httpURLConnection.setDefaultUseCaches(false);
httpURLConnection.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded");
httpURLConnection.setRequestMethod("POST");

//EXCEPTION IS THROWN HERE!
DataOutputStream outputStream = new DataOutputStream(
httpURLConnection.getOutputStream());

这考虑了什么样的联系？
什么是RSA Premaster Secret？
我应该从哪里开始寻找/学习以了解最新情况？

谢谢！

今天我的网络应用程序遇到了类似的问题。系统管理员工作人员在不问任何人的情况下更新了Java版本。经过几个小时的搜索，我发现了一些有用如果您仍然感兴趣，请点击链接： https://community.oracle.com/thread/1533888

解决方案：只需从服务器类路径中删除更新的java版本，然后尝试安装旧的Java版本。
