             Summary: Jena TDB doesn't seem to release all file handles when 
dataset is closed
                 Key: JENA-775
                 URL: https://issues.apache.org/jira/browse/JENA-775
             Project: Apache Jena
          Issue Type: Bug
          Components: TDB
    Affects Versions: TDB 1.0.2
         Environment: Windows
            Reporter: Matthew Jarvis


Jena TDB doesn't allow renaming of a TDB directory after a dataset has been 
opened and a model has been added.  It appears as though there is an open file 
handle that is preventing the rename from succeeding.  The following JUnit test 
fails:

import java.io.File;
import junit.framework.Assert;
import org.junit.Test;
import com.hp.hpl.jena.query.Dataset;
import com.hp.hpl.jena.rdf.model.Model;
import com.hp.hpl.jena.tdb.StoreConnection;
import com.hp.hpl.jena.tdb.TDBFactory;
import com.hp.hpl.jena.tdb.base.file.Location;
import com.hp.hpl.jena.vocabulary.RDFS;

@Test
public void testRename() {
        String path = "C:\\tmp\\indexTdb";
        Dataset ds = TDBFactory.createDataset(path);
        StoreConnection.make(path);
        Model model = ds.getNamedModel(RDFS.Class.getURI());
        ds.addNamedModel(RDFS.Class.getURI(), model);
        ds.close();
        StoreConnection.release(new Location(path));
        File tdbRename = new File(path);
        Assert.assertTrue(tdbRename.renameTo(new 
File("C:\\tmp\indexTdbMoved")));
}
