Clojure user here. What I find really annoying what came from the Java world: - JAR dependencies and dependency hell. My project.clj is usually full of exclusions, forcing versions and stuff like this. - Logging. Oh my, how I hate everything about logging, from terribly documented .properties files, even worse documented logback.xml files, to appenders which drop messages at peak times and this log4j/slf4j mess. On the other hand, startup times are ok. The biggest problem wrt to startup times is the nrepl-refactor JAR which I load in some profiles for refactoring features in CIDER. Probably not worth it.
