Honestly, since we don't need to run any tests inside the container, it makes more sense for us to do what we're now planning to do, which is to launch and shutdown the server via Docker, and then just run ordinary JUnit tests. For your information, I've seen this 'stuck on shutdown' both with the exam-maven-plugin and using the karaf container from Junit. I wouldn't be surprised to learn that we've coded something wrong. or that Junit has a bug. Or that we've got an infestation of gremlins. If you or any of the others happen to look at the thread dumps I posted and glean some insight, you might be able to give David some relief. > regards, Achim > > > 2016-10-25 20:12 GMT+02:00 Benson Margulies <[email protected]>: > >> >> >> On Tue, Oct 25, 2016 at 1:58 PM, 'Achim Nierbeck' via OPS4J < >> [email protected]> wrote: >> >>> Hi, >>> >>> I haven't seen stuck Karafs now for a long time.
