Not even providing a
DecisionTableConfiguration dtConf =
KnowledgeBuilderFactory.newDecisionTableConfiguration();
in the call to
kBuilder.add( resource, resourceType, dtConf );
fixes this; you actually have to provide a value for the
DecisionTableInputType although XLS is a very reasonable default!
dtConf.setInputType( DecisionTableInputType.XLS );
Filing a JIRA now.
