second load

[Boris Garbuzov <bo...@borealissoft.com>]

When I try to load the same document second time (first is fine) by
means of transformer, it prints me the following 2 stack traces. Is it
another failure of Jaxp driver and I should use original Xerces API
(document.parse()) or it looks like my API misuse? Can I resue
transformer or I should reconstract it each time? Can I reload document
by calling parse() second time?

    /**
    called from load()

    private Node loadNodeFrom (Node node, File file)
    {
        try
        {
            InputStream in = new FileInputStream (file);
            Source streamSource = new StreamSource (in);
            Result domResult = new DOMResult (node);
            transformer.transform (streamSource, domResult);
            System.out.println ("loaded from " +
file.getCanonicalPath());
        }
        catch (Exception ex)
        {
            assert ("", ex);
        }
        return node;
    }
