--------------------------

             Summary: AutoDetectParser wrongly detects plain text as images/audio
                 Key: TIKA-1770
                 URL: https://issues.apache.org/jira/browse/TIKA-1770
             Project: Tika
          Issue Type: Bug
          Components: parser
    Affects Versions: 1.10
         Environment: OS independent (tested on both Windows, MAC OS)
            Reporter: Ziqi
            Priority: Minor


AutoDetectParser fails to recognize certain plain-text files as plain text.

In the attachment are three testing files, as you can see they are all plain text.

The following code is used for testing:

————————
AutoDetectParser parser = new AutoDetectParser();
for (File f : new File("path").listFiles()) {
    InputStream in = new BufferedInputStream(new FileInputStream(f.toString()));
    BodyContentHandler handler = new BodyContentHandler(-1);
    Metadata metadata = new Metadata();
    try {
        parser.parse(in, handler, metadata);
        String content = handler.toString();
        System.out.println(metadata); //line A
    }catch (Exception e){
        e.printStackTrace();
    }
}
————————
for the three testing files, line A prints the following:
X-Parsed-By=org.apache.tika.parser.EmptyParser Content-Type=image/x-portable-bitmap 
X-Parsed-By=org.apache.tika.parser.DefaultParser X-Parsed-By=org.apache.tika.parser.mp3.Mp3Parser xmpDM:audioCompressor=MP3 Content-Type=audio/mpeg 
X-Parsed-By=org.apache.tika.parser.EmptyParser Content-Type=image/x-portable-bitmap 

And as a result, variable "content" is always empty.
