> A minor initilization issue
> ---------------------------

> Issue Type: Bug
> Components: Core
> Environment: java8(1.8.0_152), jena-arq:3.12.0
> Reporter: ssz
> Priority: Minor
>
> The following one-class program fails with assertion error:

> {code:java}
> package xx.yy;
> import org.apache.jena.rdf.model.RDFNode;
> import org.apache.jena.rdf.model.ResourceFactory;
> import org.apache.jena.sys.JenaSubsystemLifecycle;

> @Override
> public void start() {
> if (JenaSystem.DEBUG_INIT)
> System.err.println("InitTEST -- start");
> assert RDF.type != null : "RDF#type is null => attempt to load a
> graph here will fail";
> }
> @Override
> public void stop() {
> if (JenaSystem.DEBUG_INIT)
> System.err.println("InitTEST -- finish");
> }
> @Override
> public int level() {
> return 500;
> }
> public static void main(String... args) { // run VM option: -ea
> JenaSystem.DEBUG_INIT = true;
> //RDFNode r = ResourceFactory.createProperty("X"); // this works fine
> RDFNode r = ResourceFactory.createTypedLiteral("Y"); // this causes a
> problem
> System.out.println(r);
> }
> }
> {code}
