oAuth Client Credentials Grant

Hello, I just pulled down Ready API and am trying the oAuth client crednetials grant flow from the Auth Manager wizard.  I have properly populated the Client ID, Client Secret, Access Token URI, and scope and verified the values with a home grown JUnit test.  I attempted to retrieve an access token using the "Get Access Token" button and result in the below output for each of the listed log files.

The client id and credentials are set and displayed per the following line in the HTTP log file:

grant_type=client_credentials&scope=create&client_secret=[CLIENT SECRET IS CORRECT]&client_id=bDjqy4CPfadQlpLT

I also checked to see if there was an update, but i am on the latest version of the product.

Additional Info

The oAuth server is a Spring Boot 1.3.1 app running under java 1.8.  My guess bassed on what is being logged is that the request to obtain the access token includes client_secret & client_id as parameters rather than basic auth "Authorization Basic" encoded header value - as does the home grown JUnit test. 

I am able to manually retrieve an "access token" and set it manually and SOAP UI works but this requires manual steps outside of soap ui.  Any suggestions for a correction or good work around?
