To reproduce locally, edit SmokeParserTest to test "operators.drl" intensely.


public class SmokeParserTest extends ParserTest {

    private final Logger LOGGER = LoggerFactory.getLogger(SmokeParserTest.class);

    private static int count = 0;

    public SmokeParserTest(final File file, final KieBaseTestConfiguration kieBaseTestConfiguration) {
        super(file, kieBaseTestConfiguration);
    }

    @Parameters
    public static Collection<Object[]> getParameters() {
        //        return getTestParamsFromFiles(getFiles("smoke"));
        File file = new File("src/test/resources/org/drools/testcoverage/functional/parser/smoke/operators.drl");
        List<File> files = new ArrayList<>();
        files.add(file);
        return getTestParamsFromFiles(files);
    }

    @Test
    public void testParserSmoke() {
        for (int i = 0; i < 50; i++) {
            LOGGER.warn(count++ + " : " + file.getName());
            final Resource fileResource = KieServices.Factory.get().getResources().newFileSystemResource(file);
            KieUtil.getKieBuilderFromResources(kieBaseTestConfiguration, true, fileResource);
