Adding ORDER BY to SELECT COUNT(*) FROM ... returns org.teiid.core.TeiidProcessingException: null to client - Needs clearer message
-----------------------------------------------------------------------------------------------------------------------------------

                 Key: TEIID-1399
                 URL: https://issues.jboss.org/browse/TEIID-1399
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
    Affects Versions: 7.1.1
            Reporter: Paul Nittel
            Assignee: Steven Hawkins


I had quickly queried SELECT COUNT(*) FROM  sometable ORDER BY ColA, ColB and received org.teiid.core.TeiidProcessingException: null as a result. Checking the server, I found the stack trace below. Neither actually points out the ORDER BY is incorrect since it does not reference projected columns.

A clearer message will help the users.
