JDK 1.2.2 java.security.AccessController.checkPermission(null) throws
NullPointerException while
java.security.AccessControlContext.checkPermission(null)
does not throw NullPointerException.

This is an inconsistency.
java.security.AccessControlContext.checkPermission(null)
should also throw NullPointerException.

A test example which demonstrates this problem.
===== test43.java ========
import java.security.ProtectionDomain;
import java.security.AccessControlContext;
import java.security.AccessController;


public class test43 {

   public static void main (String argv[]) {
       SecurityManager sec = new SecurityManager();
       ProtectionDomain pd[] = new ProtectionDomain[1];
       
       try {
(new AccessControlContext(pd)).checkPermission(null);
           System.out.println("CASE1: NullPointerException not thrown");
       } catch (NullPointerException npe) {
           System.out.println("CASE1: NullPointerException thrown");
       }


       try {
AccessController.checkPermission(null);
           System.out.println("CASE2: NullPointerException not thrown");
           return;
       } catch (NullPointerException npe) { //OKAY
           System.out.println("CASE2: NullPointerException thrown");
       }
       return;
  }
}
