> The KnowledgeAgentImpl does not pass through ResourceConfiguration's through to KnowledgeBuilderImpl, making the building of configuration parametrised Resources not possible. Eg, trying to compile a DecisionTable (XLS) results in a NPE:
> Caused by: java.lang.NullPointerException

> In general it would be good if the KnowledgeAgent would behave exactly as the KnowledgeBuilder under the same ChangeSet configuration.
