I've some idea, but it may not be right; I'm thinking that clojure needs its own classloader and if that spring thing overriden it somehow, it's not going to work initing clojure, just like in minecraft bukkit server with clojure-based plugins, ie. https://github.com/CmdrDats/clj-minecraft/ I'm thinking maybe you need to do something similar with temporarily restoring clojure's classloader when clojure inits or something like that (I don't remember) but you may look at the code in clj-minecraft like here: https://github.com/CmdrDats/clj-minecraft/blob/master/javasrc/cljminecraft/BasePlugin.java#L56
What clojure version were you using when the above stacktrace happened?
