Immutant was a wonderful way to deploy Clojure to Wildfly when it started, but RedHat disbanded the immutant team years ago and for at least 3 years Immutant has been incompatible with Java > 1.08, due to a transitive dependency and a dauntingly complex opensource codebase. Now I am maintaining apps that need a total server shift due to the fact that I used Immutant years ago...
