AFAIK Nifi supports JDK 1.8, other JDK versions probably will not work.

Will not restart NiFi Maybe this is an OpenJDK issue? TBH, I haven't spent nearly enough time reading the docs at this point but I thought it might just run out of the box. So, it could be operator error on my part too. Thoughts? Thanks, Matt
