As I wrote in #375 the acceptance tests are unstable in the branch it couldn't be a reliable quality gate.

I will commit this change.

(One log message is moved to the DEBUG level. I just fond that we need a new ozone insight point to easily display the pipeline related debug messages).

Thanks @timmylicheng the contribution.
