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

             Summary: org.apache.tika.sax.ToXMLContentHandler$ElementInfo.getPrefix(ToXMLContentHandler.java:58)
                 Key: TIKA-1999
                 URL: https://issues.apache.org/jira/browse/TIKA-1999
             Project: Tika
          Issue Type: Bug
          Components: parser
    Affects Versions: 1.13
         Environment: Ubuntu 16.04 (64 bit)
Oracle Java 1.8.0_91-b14 (64 bit)
            Reporter: Egbert


When trying to read the following PDF document:

http://www.arcadiz.com/content/assets/Artikel_CloudWorks_Vernieuwingen_zorg_vragen_om_veel_snellere_verbindingen.pdf

TIKA crashes for me with a java.lang.StackOverflowError, caused by a large number of recursion in:

    at org.apache.tika.sax.ToXMLContentHandler$ElementInfo.getPrefix(ToXMLContentHandler.java:58)

For some reason, the Tika App doesn't exhibit this behavior, but the following MWE exposes the issue for me:

import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileInputStream;
import org.apache.tika.metadata.Metadata;
import org.apache.tika.parser.AutoDetectParser;
import org.apache.tika.parser.ParseContext;
import org.apache.tika.sax.ToHTMLContentHandler;

public class test
{
    public static void main(String [] args) throws Exception {
        String p = "/home/eggie/faulty_pdf_document.pdf";
        
        FileInputStream input = new FileInputStream(new File(p));
        AutoDetectParser tk = new AutoDetectParser();
        ByteArrayOutputStream os = new ByteArrayOutputStream();
        ToHTMLContentHandler handler = new ToHTMLContentHandler(os, "UTF-8");
        ParseContext pc = new ParseContext();
        System.out.println("Parsing");
        tk.parse(input, handler, new Metadata(), pc);
    }
}
