I'm seeing this too but with the message

mranderson048.orchard.v0v3v0.dynapath.v0v2v5.dynapath.defaults$eval1644$fn__1645 to method java.net.URLClassLoader.addURL(java.net.URL)

As of 1.0.0, dynapath doesn't extend URLClassLoader due to this Java 9 restriction (see https://github.com/tobias/dynapath#note-on-urlclassloader).

@based2 For boot, I believe the issue is boot's aether lib brings in pomegranate 1.0.0, which brings in an older dynapath - having boot instead use pomegranate 1.1.0 should resolve this, since it uses dynapath 1.0.0.

@camsaul The cider issue is a known one, but doesn't have a solution at the moment: https://github.com/clojure-emacs/orchard/issues/20
