[rules-users] Unknown execution error: jitting

[David R Robison]

Here is the original rule

1. 	| 	rule "Select closest upstream VMS Sign on same route"
2. 	| 	salience -200
3. 	| 	no-loop true
4. 	| 	dialect "mvel"
5. 	| 	when
6. 	| 	        not IncidentWithVmsSign()
7. 	| 	        $incident : Incident()
8. 	| 	        $incidentRoutingIncreasing : RoutingIncreasing(routeName 
== $incident.routeName)
9. 	| 	        $sign : VmsSign($incident.routeName == routeName)
10. 	| 	        not VmsSign(($incidentRoutingIncreasing.isIncreasing && 
$sign.routeMileMarker > routeMileMarker) || 
(!$incidentRoutingIncreasing.isIncreasing && $sign.routeMileMarker < 
routeMileMarker))
11. 	| 	then
12. 	| 	        insert(new IncidentWithVmsSign($incident, $sign));
13. 	| 	end


Any thoughts would be helpful. David
