> There's an OutOfMemory exception when adding data to the TDB model with the following code:
> public class JenaAddPerfTest {
>     private Model model;
>     private Resource cls;
>     
>     @Before
>     public void init() {
>         File file = new File(System.getProperty("java.io.tmpdir")+"/test-"+UUID.randomUUID().toString());
>         file.mkdirs();
>         
>         model = TDBFactory.createModel(file.getAbsolutePath());
>         cls = model.createResource("http://example.com/class");
>         cls.addProperty(RDF.type, OWL.Class);
>         cls.addProperty(RDFS.subClassOf, OWL.Thing);
>     }
>     
>     @After
>     public void close() {
>         model.close();
>     }
>     
>     @Test
>     public void test() {
>         for (int i=0; i<10000000; i++) {
>             model.createResource("http://example.com/res"+i, cls);
>             if (i%10000 == 0) {
>                 System.out.println(i);
>             }
>         }
>     }
> }
> The exception happens after ~670000 iterations with -Xmx128m.
