Description

Encountered this after updating an old test harness to the latest libraries:

Exception in thread "main" java.lang.NullPointerException
	at org.apache.jena.riot.adapters.AdapterFileManager.readModelWorker(AdapterFileManager.java:288)
	at org.apache.jena.util.FileManager.loadModelWorker(FileManager.java:305)

	at com.cray.km.arq.TestDAWG.suite(TestDAWG.java:55)
	at com.cray.km.arq.TestDAWG.main(TestDAWG.java:46)

The NPE occurs because the Code fails to check that the input stream isn't null
