For a reason I haven’t determined yet: Clojure java interop uses different syntax for static methods…

(.member Instance args) ;; Normal object access
(Classname/StaticMember args*) ;;static class access

Both expand to the same form -> (. instance/class member [args]), so my guess would be the (.member ...) shorthand does some runtime reflection checking that is not possible with static methods? Hmmm…. will have check the source soon :P
