Partial Code:-

@PerformInSession

public void addACLPermiForGroup(final String groupName, final String path, final String privilege)

        throws UserPersistenceException {

    try {

        UserManagerWrapper userManagerWrapper = userManagerWrapperFactory.createUserManagerWrapper();

        AccessControlManager aMgr = accessControlManagerFactory.createAccessControlManager();

        AccessControlList acl;

        for (String strPath : path.split(PATH_CONFIG_SEPARATOR)) {

            AccessControlPolicyIterator acplItr = aMgr.getApplicablePolicies(strPath);

            if (acplItr.hasNext()) {

                // get first applicable policy (for nodes w/o policy)

               acl = (AccessControlList) acplItr.nextAccessControlPolicy(); // Exception is thrown at this line

            } else {

                // else node already has a policy, get that one

                acl = (AccessControlList) aMgr.getPolicies(strPath)[0];

            }

            for (AccessControlEntry e : acl.getAccessControlEntries()) {

                Principal p = e.getPrincipal();

                if (e.getPrincipal().equals(userManagerWrapper.getExistingAemGroup(groupName).getPrincipal()))

                {

                    acl.removeAccessControlEntry(e);

                }

            }

           String[] privilegeNames = privilege.split(PATH_CONFIG_SEPARATOR);

            Privilege[] privileges = new Privilege[privilegeNames.length];

            for(int i=0; i < privileges.length; i++)

            {

                privileges[i] = aMgr.privilegeFromName(privilegeNames[i]);

            }

            acl.addAccessControlEntry(

                    userManagerWrapper.getExistingAemGroup(groupName).getPrincipal(), privileges);

            aMgr.setPolicy(strPath, acl);

        }

    } catch (RepositoryException e) {

        throw new RetryableRepositoryException(String.format(

                "Failed to add %s ACL permission to %s for %s", privilege, path, groupName, e));

    }

}
