Description

Hi there

We have decided to remove support for some formats when using Tika to extract text and metadata.

We defined our list of Parsers:

    private static final Parser PARSERS[] = new Parser[] {
        // documents
        new org.apache.tika.parser.html.HtmlParser(),
        new org.apache.tika.parser.rtf.RTFParser(),
        new org.apache.tika.parser.pdf.PDFParser(),
        new org.apache.tika.parser.txt.TXTParser(),
        new org.apache.tika.parser.microsoft.OfficeParser(),
        new org.apache.tika.parser.microsoft.OldExcelParser(),
        new org.apache.tika.parser.microsoft.ooxml.OOXMLParser(),
        new org.apache.tika.parser.odf.OpenDocumentParser(),
        new org.apache.tika.parser.iwork.IWorkPackageParser(),
        new org.apache.tika.parser.xml.DcXMLParser(),
        new org.apache.tika.parser.epub.EpubParser(),
    };

    private static final AutoDetectParser PARSER_INSTANCE = new AutoDetectParser(PARSERS);

    private static final Tika TIKA_INSTANCE = new Tika(PARSER_INSTANCE.getDetector(), PARSER_INSTANCE);

But when a MS Office Word document embeds another non supported document (Like a Visio Schema) an NoClassDefFoundError is raised.

Would it be possible to catch such a case and throw in that case a TikaException so it behaves as an Exception and not as a Throwable?
