I updated my fork to the latest this morning to do some testing and have been
getting the below error on startup.
My first assumption was a build issue on my end so I cleaned out the NiFi MVN
cache on my box and built again, but I'm still getting this error.
I've only tested this on my Windows box. Thoughts?
