The stacktrace should be pointing to the correct file & line number -- no need to reverse engineer the mangling. If it's not for some reason, file a bug. (It's helpful to eliminate nREPL / lein middleware in case something is transforming the printing of traces) If you are missing a trace when the JVM JITs your code, run with -XX:- *OmitStackTraceInFastThrow*
