>  class RunEngine implements Runnable { 
> @Override public void run() { campaignEngine.fireUntilHalt(); } } 
> NOTE: This occurs on a new system where nothing has been persisted to the database. In other words, there isn't a session available to be loaded. I have yet to have success reloading a session - that is a separate issue that I believe DROOLS-422 partially identifies.
