            Subject s2 = new Subject(false, hash2, hash2, hash2);
 
            Subject s3 = new Subject();
 
            notEqual = new Vector();
             
            notEqual.add(s1.getPrincipals());
            notEqual.add(s1.getPrivateCredentials());
            notEqual.add(s1.getPublicCredentials());
