I'm not sure I understand your question. What you mean by "OSGI related stuff."?
SMX4 basically is a OSGi container which support lot of technologies/components out of the box.
If you need configure threadpool, you just configure each component your want, something like camel/jetty/jbi/nmr separately, as they all work in OSGi container, so they're just OSGi stuff.
Thanks Freeman!! I am clear now.
