Java安全管理器异常

Question

我正在开发一个使用 Java 授权和身份验证服务 (JAAS) 的项目。不过，我遇到了一个奇怪的安全异常:

Caused by: java.security.AccessControlException: access denied ("java.lang.RuntimePermission" "accessClassInPackage.sun.security.util")

我无法理解这个异常的含义。此外，即使我向应用程序授予所有权限，我也会遇到相同的异常

  permission java.security.AllPermission;

来自here :

The java.lang.SecurityManager.checkPermission(Permission perm, Object context) method throws a SecurityException if the specified security context is denied access to the resource specified by the given permission. The context must be a security context returned by a previous call to getSecurityContext and the access control decision is based upon the configured security policy for that security context.

SecurityManager由本地系统配置，SecurityManager负责保护本地系统
