我有一个应用程序，使用RMI和工作时，我有安全策略设置为
//
// Allow everything for now
//
permission java.security.AllPermission;
但是，当我试图用下面的策略锁定它时，我得到了这个异常-这让我认为类路径的某些内容是关闭的，我需要在策略中添加一些关于类路径的内容，但我不知道是什么。
也-任何想法为什么我必须设置套接字权限所有不同的方式(环回，名称，基础ip)?

};
解决这个问题的方法是在我的策略文件中添加以下行:
permission java.lang.RuntimePermission "getClassLoader";
