[rules-users] Unknown execution error: jitting

[David R Robison]

I have a rule that runs fine when I execute it inside Guvnor in a Test 
Scenario but when I run it in production I get the following error.

Exception in thread "Thread-24" java.lang.RuntimeException: Exception 
jitting: $incidentRoutingIncreasing.isIncreasing && 
$sign.routeMileMarker > routeMileMarker || 
!$incidentRoutingIncreasing.isIncreasing && $sign.routeMileMarker < 
routeMileMarker

The rule does seem to fire. Any idea what it is trying to tell me or any 
hints on how to debug this?
