[rules-users] Optaplanner: Unexpected global [scoreHolder] - Kie API trouble

[Geoffrey De Smet]

I presume you're building your own KieBase and setting it with 
setKieBase() ?

If so, that KieBase is empty or corrupted or something, but it doesn't 
fail-fast either apparently.
Look at this code for inspiration (that's where I ran into it too):
https://github.com/droolsjbpm/optaplanner/blob/master/optaplanner-core/src/main/java/org/optaplanner/core/config/score/director/ScoreDirectorFactoryConfig.java#L299

Please let us know what exactly the problem was here on the mailing list.
I want to create a jira for DROOLS to fail-fast during KieBase 
construction when a misconfiguration happens.
