ClassCastException during constraint jitting when an interface is used for implementation and traiting ------------------------------------------------------------------------------------------------------ Key: DROOLS-291 URL: https://issues.jboss.org/browse/DROOLS-291 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 5.5.0.Final, 6.0.0.CR4 Reporter: Davide Sottara Assignee: Mario Fusco Priority: Critical The following combination is needed: - an interface IX with at least one getter/setter pair - a trait IY extending IX - a class K implementing IX - a jittable constraint on IX The constraint is first triggered by an "instance" of IY, but jitted by an instance of K. The condition analyzer assumes that IY is the natural domain of the constratint, rather than IX. The jitted constraint will then try to cast K to IY, resulting in a disruptive CCE
