jena-text and persistent lucene index

Jena crew:

I have Jena-Text pretty much working for what I want to do, but with
one caveat... it only seems to work with the Lucene RamDirectory. If
I use a persistent dir, I don't find any documents being written to
the Lucene index. Any help or suggestions are greatly appreciated.
Code sample follows:

---CODE---

package org.fogbeam.example.jenatext

import org.apache.jena.query.text.EntityDefinition
import org.apache.jena.query.text.TextDatasetFactory
import org.apache.jena.query.text.TextQuery
import org.apache.lucene.store.Directory
import org.apache.lucene.store.FSDirectory

import com.hp.hpl.jena.query.Dataset
import com.hp.hpl.jena.query.ReadWrite
import com.hp.hpl.jena.rdf.model.Model
import com.hp.hpl.jena.rdf.model.Resource
import com.hp.hpl.jena.rdf.model.Statement
import com.hp.hpl.jena.tdb.TDBFactory
import com.hp.hpl.jena.vocabulary.RDFS

class JenaTextMain6Write

static main(args)

TextQuery.init();

EntityDefinition entDef = new EntityDefinition("uri", "text",
RDFS.label.asNode()) ;

// Lucene, in memory.
Directory dir = FSDirectory.open( new File( "jenastore/index" ) );

// Join together into a dataset
Dataset tdbDataset = TDBFactory.createDataset("jenastore/triples");
Dataset ds = TextDatasetFactory.createLucene(tdbDataset, dir, entDef);

try

ds.begin(ReadWrite.WRITE);

Model m = ds.getDefaultModel();

Resource rSubject = m.createResource(
"http://ontology.fogbeam.com/example/TestResource1" );
Resource rSubject2 = m.createResource(
"http://ontology.fogbeam.com/example/TestResource2" );

Statement s = m.createStatement(rSubject, RDFS.label,
"This is a Test Resource" );

m.add( s );

Statement s2 = m.createStatement(rSubject2, RDFS.label,
"Bratwurst Test" );

m.add( s2 );

ds.commit();

dir.close();

catch( Exception e )

e.printStackTrace();
ds.abort();

finally

if( ds != null )

ds.end();

println "done";
