The javadoc does not specify behavior of
java.security.AccessControlContext.checkPermission(null).
checkPermission() tries to check if null permission is
implied by context which does not make sense.
It should throw NullPointerException.

A test example which demonstrates this problem.
===== test44.java ========
import java.security.*;

public class test44 {

   public static void main (String argv[]) {
       SecurityManager sec = new SecurityManager();
       ProtectionDomain pd[] = new ProtectionDomain[1];
       AccessControlContext acc = new AccessControlContext(pd);
       
       try {
           acc.checkPermission(null);
           System.out.println("Failed: NullPointerException expected");
           return;
       } catch (NullPointerException npe) { //OKAY
       }

       System.out.println("Passed.");
       return;
  }
}

========= Sample run (JDK1.2.1) ==========
#>java test44
Failed: NullPointerException expected
