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）。 应用程序中的屏幕之一接近Webshere，该Webshere通过HTTPS安装在远程服务器上。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，一切都很好：握手成功完成，消息发送到服务器，返回的代码为200（确定）。 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）协同运行时，会抛出“ javax.net.ssl.SSLKeyException：RSA premaster秘密错误”
通过卸载并重新安装所有Java版本，可以解决Internet上大多数类似的问题。但是我的Java没有安装，所以我不能这样做。
我检查了三倍，以确保我的Java应用程序使用了正确的jre。
我不知道是什么原因导致此异常，我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：

任何信息都值得赞赏。
解决方法
就像在较早的帖子中提到的许多关于异常的人一样
javax.net.ssl.SSLKeyException：RSA premaster机密错误
表示两个不同的Java版本混合在一起。因此，重新安装Java会有帮助。
在我看来，dotnet应用程序将Java扩展文件夹设置为较旧的Java版本。将扩展名配置设置为正确的Java版本后，问题已解决。
