-------------------------------------

              Summary: Location mapping doesn't work properly when preceded
by calling DatasetFactory#createMem
                  Key: JENA-509
                  URL: https://issues.apache.org/jira/browse/JENA-509
              Project: Apache Jena
           Issue Type: Bug
           Components: Jena
     Affects Versions: Jena 2.10.1
             Reporter: Piotr Hołubowicz
          Attachments: jena-509.zip

The following code works in Jena 2.10.0.

{code}
         String TEST_RESOURCE = "http://example.org/test.ttl";;
         Dataset dataset = DatasetFactory.createMem();
         Model model = FileManager.get().loadModel(TEST_RESOURCE,
TEST_RESOURCE, "TURTLE");
{code}

In Jena 2.10.1 the location-mapping.n3 resource doesn't seem to work and
the following exception is thrown:

{code}
com.hp.hpl.jena.shared.NotFoundException: Not found:
http://example.org/test.ttl
         at
org.apache.jena.riot.adapters.AdapterFileManager.readModelWorker(AdapterFileManager.java:285)

         at com.hp.hpl.jena.util.FileManager.loadModel(FileManager.java:296)
...
{code}

In Jena 2.10.2-SNAPSHOT the exception is different, presumably due to the
fix to JENA-505:

{code}
org.apache.jena.atlas.web.HttpException: 404 - Not Found
