[rules-users] Runtime Java Exception - Firing rules (Drools Expert 5.2.1).

[groovenarula]

Hello all,

We're getting the following exception executing our rules in Drools 5.2.1 :

The issue is that I can't seem to find the class
org.drools.factmodel.traits.Thing in any Drools 5.2.1 modules.

Can someone tell me the possible causes?

Thanks in advance
