Michael Neale closed JBRULES-1650.
----------------------------------

    Resolution: Won't Fix


A restart is required due to the way jackrabbit works at this time, unfortunately. Due to all the caching that goes on, a deploy of the BRMS war on the fly is not recommended without a restart (the same applies to most apps).
