Thanks for your clarification. @kimbarrett 

I'd like to post the configuration info of my local test environment here.

As the Oracle CI log is not available to me, I wonder if you could help make a comparison between my config and that in Oracle CI? 
And please feel free to let me know if we need more info. 
Thanks.
