I really don't know how to get this inline code covered. As It has tests but jacoco is ignoring it :(

This is a known issue jacoco/jacoco#654, I don't really want to trade the benefits of inline by code coverage. I'm not quite sure what should I do here.

Looks great! One comment / change request for the concept engine bits.
