The source code of the method.
It fails at ( writer.optimize();// This is where it fails), which is not
within a try/catch.
It works great with the lucene-1.2 version but fails with the
lucene-1.3-final.jar
Any ideas would be appreciated.
Apologies for posting this question to the dev list initially.

----                     code            ----
public synchronized void index() throws Exception {
        final ProductDocumentBuilder productDocument =
ProductDocumentBuilder.getInstance();
        productFactory = new ProductFactory(productHome, pgroupHome);

        registerDocumentBuilder("ml.product", productDocument);
        registerFactory("ml.product", productFactory);

        logger.info("index() starting.");

        logger.info("  loaded data, indexing");

        // create the indexer
        IndexWriter writer = new IndexWriter(workDir, new
StandardAnalyzer(), true);
        writer.mergeFactor = mergeFactor;
        long start = System.currentTimeMillis();
        // pass in a dummy new Object
        Iterator allProducts = productFactory.contentIterate(new Object());
        int i = 0;
        while (allProducts.hasNext()) {
            i++;
            SearchProduct product = (SearchProduct) allProducts.next();
            try {
                writer.addDocument(productDocument.getDocument(product));
            } catch (Exception e) {
                logger.warn("Failed to index Product: " + product.getPK(),
e);
            }
        }

        writer.optimize();// This is where it fails
        writer.close();
        logger.info("  indexer took " + (System.currentTimeMillis() -
start) + " milliseconds. To  index " + i + " products ");
        productFactory.flush();
    }
--           end code -------------------
