Description

I noticed a new NPE in one of our test files on Tika when I recently built PDFBox's trunk. I've attached the file.

If I don't set strict parsing to false, the parse works.

        DomXmpParser xmpParser = new DomXmpParser();
        xmpParser.setStrictParsing(false);
        Path p = Paths.get(".../metadata.xml");
        try (InputStream is = Files.newInputStream(p)) {
            XMPMetadata metadata = xmpParser.parse(is);
            for (XMPSchema schema : metadata.getAllSchemas()) {
                for (AbstractField f : schema.getAllProperties()) {
                    System.out.println(f);
                }
            }
        }
