Description

Hey, I'm trying to get content of a text file (mysql config file).

	public void testTikaParserUtils() throws Exception {
		String resourceLocation = "files/my.cnf";
		String content = ParseUtils.getStringContent(new File(resourceLocation), new TikaConfig());
		System.out.println(content);
	}

OR

	public void testTikaParserUtils() throws Exception {
		String resourceLocation = "files/my.cnf";
		String content = ParseUtils.getStringContent(new File(resourceLocation), TikaConfig.getDefaultConfig());
		System.out.println(content);
	}

but I get null pointer exception, because "parser" is null

ParseUtils.java

public static String getStringContent(
            InputStream stream, TikaConfig config, String mimeType)
            throws TikaException, IOException {
        try {
            Parser parser = config.getParser(MediaType.parse(mimeType));
            ContentHandler handler = new BodyContentHandler();
            parser.parse(stream, handler, new Metadata());
            return handler.toString();
        } catch (SAXException e) {
            throw new TikaException("Unexpected SAX error", e);
        }
    }}

It works only if I specifically determine the type of parser

	@Test
	public void testTikaParserUtils() throws Exception {
		Tika tika = new Tika(new TextDetector());
		String content = tika.parseToString(new File(txt));
		System.out.println(content);
	}
