> ImmediateComponentHolder.enableComponents has a race condition.  It sets the holder's m_enabled state last after enabling all the components it finds when it starts.  However other threads from config admin could be adding components during this time, and they will never get enabled.  Calling enable on a component twice shouldn't cause a problem, so moving setting m_enabled to the start of enableComponents should fix this.
