问题描述
在我的 Web 应用程序中，我使用了一个带签名的 jar 小程序，这个小程序在 jre 1.6 和 1.7 之前运行良好.但是在小程序安全弹出和阻止错误后，我们不得不购买一个java代码签名证书.
In my web application, I am using a applet which is signed jar and this applet was working fine before jre 1.6 and 1.7. But after security popup and blocking error of applet we had to purchased a java code signing certificate.
我已经成功签署了这个小程序 jar 并且这个小程序在 HTTP 协议上运行没有任何问题.如果我在 HTTPS 上打开这个小程序，它开始给出 SSLHandshakeException 的异常.我已经尝试了所有可能的解决方案来运行它，但它失败了.
I have signed this applet jar successfully and this applet is running without any problem on HTTP protocol. If I open this applet on HTTPS, it start giving exceptions of SSLHandshakeException. I have tried every possible solution to run this but it failed.

在小程序中，我使用的是简单的小程序
In applet, I am using simple applet
import java.applet.*;
import java.awt.*;
public class Apps extends Applet{
public void paint(Graphics g){
g.drawString("Welcome in Java Applet.",40,20);
}
}
推荐答案
我们遇到了同样的问题.我相信这是 Java 为 SSL 实现 TLS 1.2 的方式中的一个错误.
We are having this same issue. I believe this is a bug in the way Java implemented TLS 1.2 for SSL.
根据他们的文档，https://blogs.oracle.com/java-platform-group/entry/java_8_will_use_tls，他们声称通过启用 TLS 1.2，它向后兼容旧版本.
According to their documentation, https://blogs.oracle.com/java-platform-group/entry/java_8_will_use_tls, they claim that by enabling TLS 1.2, it is backwards compatible with older versions.
然而，事实并非如此.禁用 TLS 1.2 后，我们不再收到握手期间远程主机关闭连接"错误.
However, this is not the case. When TLS 1.2 is disabled, we no longer get the "Remote host closed connection during handshake" error.
可以从 Java 控制面板的高级设置中关闭 TLS 1.2 支持.
TLS 1.2 support can be turned off from the Advanced Settings in the Java Control Panel.
一旦完成，小程序就可以工作了.
Once this is done, the applets will work.
