Simon Steiner updated FOP-3269:
-------------------------------
    Description: 
Generate pdf twice with a table with 10k fo:table-body's with using -Xmx500m should not give OOM

{code:java}
public void xxx() throws Exception {
    FopConfParser fopConfParser = new FopConfParser(new File("fop.xconf"),
            new File("xxx").toURI());
    FopFactoryBuilder fopFactoryBuilder = fopConfParser.getFopFactoryBuilder();
    fopFactoryBuilder.setStrictFOValidation(false);
    FopFactory fopFactory = fopFactoryBuilder.build();
    x(fopFactory);
    fopFactory = fopFactoryBuilder.build();
    x(fopFactory);
}

private void x(FopFactory fopFactory) throws Exception {
    FOUserAgent userAgent = fopFactory.newFOUserAgent();
    Transformer transformer = TransformerFactory.newInstance().newTransformer();
    Source src = new StreamSource(new FileInputStream("out.if"));
    IFDocumentHandler documentHandler
            = userAgent.getRendererFactory().createDocumentHandler(userAgent, MimeConstants.MIME_PDF);
    documentHandler.setResult(new StreamResult(new NullOutputStream()));
    IFUtil.setupFonts(documentHandler);
    IFParser parser = new IFParser();
    Result res = new SAXResult(parser.getContentHandler(documentHandler, userAgent));
    transformer.transform(src, res);
}
{code}
