Blazegraph test 1

BlazegraphTest1

The embedded driver:
public class EmbeddedDriver implements IGraphDriver {
	private JSONGraphStoreEnvironment environment;
	//TODO make this a config property
	private final String DBPATH = "/data/bg/mygraphjournal";
	private BigdataGraph _MyGraph;

	public EmbeddedDriver() {}
	
	@Override
	public IResult init(JSONGraphStoreEnvironment env) {
		IResult result = new ResultPojo();
		environment = env;
		try {
			_MyGraph = BigdataGraphFactory.open(DBPATH, true);
			System.out.println("GRAPH "+_MyGraph);
		} catch (Exception e) {
			environment.logError(e.getMessage(), e);
			result.addErrorString(e.getMessage());
		}
		return result;
	}
	@Override
	public BigdataGraph getGraph() {
		return _MyGraph;
	}
	@Override
	public void shutDown() {
		_MyGraph.shutdown();
	}
}

The test:
public class FirstGraphTest {
	private JSONGraphStoreEnvironment environment;
	private final String example = "data/examples/graph-example-1.xml";
	
	public FirstGraphTest() {
		environment = new JSONGraphStoreEnvironment();
		EmbeddedDriver d = new EmbeddedDriver();
		IResult r = d.init(environment);
		
		BigdataGraph graph = d.getGraph();
		try {
			GraphMLReader.inputGraph(graph, example);
			for (Vertex v : graph.getVertices()) {
				System.err.println(v);                
            }      
            for (Edge e : graph.getEdges()) {  
                System.err.println(e);
            }		
		} catch (IOException e) {
			e.printStackTrace();
		}
		d.shutDown();
		System.out.println("Fini "+r.getErrorString());
	}
}

Data?

The only data in the mix is the same blueprints gml graph used in your unit tests. There was, in fact, data in the journal, some 10,000 kb of it; I suppose I could zip it up and send it somewhere. But, in fact, if I run the system with create = true and an empty journal directory, it does not make one, but runs fine. The moment I actually drop an empty file with the journal's name in the directory, it fills it with background data, then blows up while reading the gml.
