> There is a simple testcase as following. For RI, it will print the message as the implies
method will return true while our java 6 branch would return false. Obviously, our behavior
is incorrect since "exitVM" should be "implied by" "exitVM". I've got a fix for this bug.
> import java.security.Permission;
> public class TestRuntimePermission {
>     /**
>      * @param args
>      */
>     public static void main(String[] args) {
>         Permission permission_exitVM = new RuntimePermission("exitVM");
>         if(permission_exitVM.implies(new RuntimePermission("exitVM"))) {
>             System.out.println("exitVM implies exitVM");
>         }
>         
>     }
> }
