has anyone already tried to run leiningen with recently released java 9? 1. I tried to edit lein script for my current stable lein 2.7.1 installation to include this LEIN_SKIP_BOOTCLASSPATH thing: https://github.com/technomancy/leiningen/commit/151fbb256dd2919fb5d3a51136e8d441802267b2 but no success

lein repl
Exception in thread "main" java.lang.ClassNotFoundException: sun.misc.Launcher, compiling:(dynapath/defaults.clj:29:3)

I've also tried to remove everything from my ~/.lein/profiles.clj and generate new empty project. I ended up with this error:

nREPL server started on port 64092 on host 127.0.0.1 - 
java.lang.IllegalStateException: Could not find a suitable classloader to modify from clojure.lang.LazySeq@d35aa420
 at cemerick.pomegranate$add_classpath.invokeStatic (pomegranate.clj:54)

I was told that if you upgrade to the latest lein and use clojure 1.9 it should all work (haven't been able to check myself)

I switched back to java 1.8.131 for a while. I'll try again in few days or weeks:).
