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.
