Looks like an NPE in your rule.
Maybe maintenanceSlot or something is null.
You should raise an issue with drools-core (drools expert) that it
should give a better runtime error to show on which line it NPE'ed.
With kind regards,

Hi.
I am experiencing the following exception:
org.drools.RuntimeDroolsException: Exception executing ReturnValue
constraint org.drools.rule.returnvaluerestrict...@a5f6c234 :
java.lang.NullPointerException.
The rule that is causing the exception to occur is the following:
rule "spreadOvertime"
