【问题描述】：
我有一个使用 Java 8 u161 的基于 Swing 的 Java 应用程序。 应用程序使用的 jre 存储在其目录之一中（它不使用已安装的 jre）。 应用程序中的一个屏幕通过 HTTPS 接近安装在远程服务器上的 Webshere。公钥安装在客户端的 jre\lib\security 文件夹中的 cacert 上。
当应用程序作为独立应用程序运行时，一切正常：握手成功完成，消息发送到服务器，返回代码为 200（OK）。 但是，当应用程序与另一个应用程序（将代码注入 Java 应用程序的 dotnet 应用程序。我什至不确定到底是什么）协作运行时，会抛出“javax.net.ssl.SSLKeyException: RSA premaster secret error”
互联网上的大多数类似问题都是通过卸载并重新安装所有 Java 版本来解决的。但是我的Java没有安装，所以我不能这样做。
我检查了我的 Java 应用程序是否使用了正确的 jre - 它确实使用了三倍。
我不明白是什么导致了这个异常，也不知道还要检查什么。
这是我打开连接的方式：
URL servletUrl = new URL(urlStr); //throws java.net.MalformedURLException
HttpsURLConnection.setDefaultHostnameVerifier(new ChequesServletHostnameVerifier());
servletConnection = (HttpsURLConnection) servletUrl.openConnection(); //throws java.io.IOException
servletConnection.setDoOutput(true);
servletConnection.setUseCaches(false);
OutputStream os = servletConnection.getOutputStream(); //throws java.io.IOException
这是完整的堆栈跟踪：
