You're missing a # here. You create a new thread object passing two args to the Thread constructor: The return value of (println ...) and "tName". println returns nil, so you effectively do (Thread. nil "tName"). The difference in behavior is, that the first version runs the println in the repl thread BEFORE spawning a new thread (which doesn't do anything in this case). You want to pass a Runnable object (e.g. a function) as the first argument: (.start (Thread. #(println "Ohai!"), "tName")). This will create a new thread which will run the supplied function which will print a message to the console. Background threads usually print to the console because *out* etc. isn't redirected to the REPL. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
