document:null error

[zharenkov]

Hi,
I'm trying to run DOM creation, as in example on sourceforge project page, but in result my Document object doesn't have any DOM.

        PDDocument pdDocument = PDDocument.load(new FileInputStream(new File(ClassLoader.getSystemClassLoader().getResource("tst.pdf").getFile())));
        PDFDomTree tree = new PDFDomTree(PDFDomTreeConfig.createDefaultConfig());
        Document d = tree.createDOM(pdDocument);
        System.out.println(d);

The output is

[#document: null]

What i'm doing wrong?

Thanks.
