Java安全管理器异常

Question

I am working on a project using the Java Authorization and Authentication Service (JAAS). I am encountering a strange security exception though:

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

I cannot manage to understand what is the meaning of this exception. Besides, I am getting the same exception even if I grant the application all the permissions with

  permission java.security.AllPermission;

Answer 1

From 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.

The SecurityManager is configured by the local system and SecurityManager is responsible to protect the local system
