NullPointerException happening on RecordsFactory.getRecords() #6
Description
On RecordsFactory, within the method "getRecords", there is a check to see if the given reference formulation found in the mapping file is actually supported by the mapper. In the case of a non-supported reference formulation found, the code logs an error and leaves the execution run without returning from the method or throwing a controlled error.
// Select the Record Factory based on the reference formulation. if (!referenceFormulationRecordFactoryMap.containsKey(referenceFormulation)) { logger.error("Referenceformulation {} is unsupported!", referenceFormulation); } ReferenceFormulationRecordFactory factory = referenceFormulationRecordFactoryMap.get(referenceFormulation); records = factory.getRecords(access, logicalSource, rmlStore);
Instead what happens is a factory is tried to be retrieved and use this reference, which leads to a NullPointerExcepcion that in turn gets propagated all the way up the Executor class. This happens between lines 138 and 142 of the class RecordsFactory.
