Clojurians Log v2

@alandipert is there a specific reason boot is compiled with clojure v1.6?

@flyboarder I think it might have to do with AOT/bytecode compatibility but not 100% certain

@martinklepsch seems clojure used to throw Exceptions more often than it does now, bumping to 1.9 fails tests

all related to expecting exceptions that no longer exist

@micha do you know why we are pinned to 1.6?

I think moving to clojure spec would be a better testing system then what we have now

hmm, i am not sure about the 1.6 question
