> JSON production functions like JSONOBJECT and JSONARRAY_AGG seem to be still returning a clob object rather than a 'json' object even though Teiid has the first class data type for json now.
> for ex:
> {code}
> CREATE VIRTUAL PROCEDURE CustomerJSON(IN p1 integer) RETURNS TABLE (json_out json) 
>   OPTIONS (UPDATECOUNT 0, "REST:METHOD" 'GET', "REST:URI" 'CustomerJson/{p1}') AS
> BEGIN
>     SELECT JSONOBJECT(JSONARRAY_AGG(JSONOBJECT(SSN, Name))) AS json_out FROM accounts.customer;
> END
> {code}
> would fail with 
> {code}
> Caused by: org.teiid.deployers.VirtualDatabaseException: TEIID40095 TEIID31080 virt.CustomerJSON validation error: TEIID31121 The expected result set of the procedure virt.CustomerJSON does not match the result set from returnable statement SELECT JSONOBJECT(JSONARRAY_AGG(JSONOBJECT(SSN, Name))) AS json_out FROM accounts.customer; use WITHOUT RETURN to indicate the statement should not be returned - The definition for virt.CustomerJSON has the wrong type for column 1.  Expected json, but was clob.
