Debugging a bit further I came to the conclusion that it's clj-stacktrace's fault that errors with certain stack frames. (run* [q] (wrongo 1 2)) ; Evaluation aborted. *e => #<ArithmeticException java.lang.ArithmeticException: Divide by zero> (clj-stacktrace.core/parse-exception *e) ; Evaluation aborted. *e => #<NullPointerException java.lang.NullPointerException> (pst *e) NullPointerException => nil So while letting clj-stacktrace parse the ArithmeticException, an NullPointerException was thrown. By tracing the functions in clj-stacktrace.core (contained in swank-clojure-1.3.4.jar) I was able to determine the throwing function call inside clj-stacktrace. The following call throws a NullPointerException. (clojure-ns "clojure.core.logic.Substitutions") ; Evaluation aborted The definition in the swank-clojure-1.3.4.jar is (defn- clojure-ns "Returns the clojure namespace name implied by the bytecode class name." [class-name] (utils/re-gsub #"_" "-" (utils/re-get #"([^$]+)\$" class-name 1))) For the given argument, the `re-get' form returns nil which causes the null pointer. It's simply not ready for getting the namespace of a protocol. I fixed the definition directly in the swank-clojure-1.3.4.jar and then wanted to write a patch against clj-stacktrace's git master branch. As it turns out, it's already fixed in there. Funnily, it was Phil himself who committed that patch written by Michael van Acken. Phil, maybe you want to release a new swank-clojure version with an updated clj-stacktrace?
