I also built the project with sbt/sbt clean compile assembly, and when
starting the master, I got the following stack trace:

I'm wondering at this point, whether or not the PR that I've opened is
actually what's necessary to get this shading done. That PR works fine for me
end to end. Perhaps we can start from there and work our way backwards seeing
what pom modifications are extraneous in what I've implemented?
