Not harmful exception at shutdown

[arichiardi]

The following exception started appearing recently when C-c in the terminal (probably related to the new shutdown hook?)

java.util.concurrent.RejectedExecutionException: Task java.util.concurrent.FutureTask@1c529dea rejected from java.util.concurrent.ThreadPoolExecutor@cf4fb77[Terminated, pool size = 0, active threads = 0, queued tasks = 0, completed tasks = 65]

I will gladly merge a patch to https://github.com/boot-clj/boot-figreload :dancer:

Hmm, I am unable to reproduce this.

[arichiardi]

It happens with:

Mon Jan 30 10:15:20 PST 2017
BOOT_CLOJURE_NAME=org.clojure/clojure
BOOT_CLOJURE_VERSION=1.9.0-alpha14
BOOT_VERSION=2.7.0

On linux if it can help.

Can you try if you can reproduce this with https://github.com/Deraen/saapas, this is how I tested this:

❯ boot repl

Starting file watcher (CTRL-C to quit)...

Writing adzerk/boot_reload/js/main.cljs to connect to ws://localhost:45105...

My case is from the command line, I will try to reproduce with sapaas
