NPE on type definition - requires restart of AsterixDB

[GoogleCodeExporter]

Reproduction:
===============
1. Define a type as described below. The output message is blank (not even an 
error) and you cannot execute *any* query prior restarting the procs.

drop dataverse kereno if exists;
create dataverse kereno;
use dataverse kereno;

create type page_info_type as open {}

create type widegroupbydata as closed {
user: string,
        action: int32,
        timespent: int32,
        query_term: string,
        ip_addr: int32,
        timestamp: int32,
        estimated_revenue: double,
        page_info: page_info_type,
        page_links: {{ page_info_type}},
user_1: string,
        action_1: int32,
        timespent_1: int32,
        query_term_1: string,
        ip_addr_1: int32,
        timestamp_1: int32,
        estimated_revenue_1: double,
        page_info_1: page_info_type,
        page_links_1: {{ page_info_type}}
}

The stack in cc.log looks as follows:
