Problem creating ConnectionProfile for OData Service

I attempted to go thru model import and query process using the OData example service http://services.odata.org/Northwind/Northwind.svc/

• was able to import via the Teiid Connection Importer, model was created
• Next attempted to create a Connection Profile so that I could preview. When I provided the URL the connection profile test ping failed with the following exception:

java.lang.RuntimeException: java.io.IOException: Server returned HTTP response code: 415 for URL: http://services.odata.org/Northwind/Northwind.svc/

I finished creating the CP, then applied it to the model. I successfully previewed the data. So potential problem with the Connection profile url validation.
