[rules-users] EvalConditionNode cannot be cast to org.drools.reteoo.RightTupleSink

[nanic23]

We are seeing this exception when trying to complete flows in wait state.

This happens after we deploy a newer release of our application.

Context:
1. we start several process that go to wait state
2. we make bug fixes to our application and deploy a new version
3. we try to resume the existing flows that are in wait state. 
4. we get this exceptions when trying to load existing session

NOTE: drools version is the same so I don't think this is a serialization
incompatibility issue.

Exception:
