启动Java Applet

Question

我有一个Web应用程序，它启动一个引用大量Jars的Java Applet。当我启动applet时，启动了Java控制台，我可以看到这些jar被下载了。在其中一个Jars中，我得到异常并且Applet加载被停止。

机器：Windows 7 - 64位

Java Plug-in 10.80.2.15

使用JRE版本1.7.0_80-b15 Java HotSpot（TM）客户端虚拟机 - 使用此JRE作为Applet已通过此JRE版本认证，我甚至尝试使用最新的JRE。

异常追踪：

我查看了Java Cache并打开了下载的jar，我可以看到该类在那里。

之前的异常是在其他一些类上，然后我删除了所有版本的Java，并重新安装了JDK 7 Update 80 32位和类错误输出。
