[rules-users] Unknown execution error: jitting

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 at org.drools.rule.constraint.MvelConstraint.executeJitting(MvelConstraint.java:219) at org.drools.rule.constraint.MvelConstraint.access$000(MvelConstraint.java:41) at org.drools.rule.constraint.MvelConstraint$1.run(MvelConstraint.java:201) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:722) Caused by: java.lang.VerifyError: (class: ConditionEvaluatorebdfa6ebae044e95bc706dfcd6f5654a, method: evaluate signature: (Ljava/lang/Object;Lorg/drools/common/InternalWorkingMemory;Lorg/drools/reteoo/LeftTuple;)Z) Expecting to find integer on stack at java.lang.Class.getDeclaredConstructors0(Native Method) at java.lang.Class.privateGetDeclaredConstructors(Class.java:2404) at java.lang.Class.getConstructor0(Class.java:2714) at java.lang.Class.getConstructor(Class.java:1674) at org.drools.rule.builder.dialect.asm.ClassGenerator.newInstance(ClassGenerator.java:173) at org.drools.rule.constraint.ASMConditionEvaluatorJitter.jitEvaluator(ASMConditionEvaluatorJitter.java:53) at org.drools.rule.constraint.MvelConstraint.executeJitting(MvelConstraint.java:217) ... 5 more The rule does seem to fire. Any idea what it is trying to tell me or any hints on how to debug this?
