Serzh: Could you give a few details about the software machine where you saw it not terminate, even after an hour? I may try collecting some info like this to add to the Clojure ticket. In particular, the outputs of the following commands.
java -version uname -a lsb_release -d time java -jar clojure-1.6.0.jar -e "(future 1) (shutdown-agents)" time java -jar clojure-1.6.0.jar -e "(future 1)" For that last one, if it runs more than 2 minutes without terminating, you can kill it. No need to wait for an hour. I have tried Ubuntu 14.04 desktop 64-bit running in a VM on my Mac, and the last command above terminates in about 60 seconds, for several different JVM versions (mostly Oracle). Yours is the first case I've heard of not terminating after about a minute, so wanted to try to reproduce that case. I think it would be good if it took the same short time to terminate as if you call shutdown-agents, even without calling shutdown-agents. I may also work on a patch for that ticket, after trying to summarize the long list of comments.
