sebastian-nagel opened a new pull request #529:
URL: https://github.com/apache/nutch/pull/529


   - switch to multi-line presentation of Metadata in ParseData::toString
   - default implementation of Metadata::toString is still single-line
   - replace StringBuffer by StringBuilder in modified methods
   
   Parsechecker will now show metadata as follows:
   ```
   $> bin/nutch parsechecker -Dplugin.includes='parse-(tika|metatags)|protocol-okhttp' http://localhost/
   fetching: http://localhost/
   ...
   Title: Apache2 Ubuntu Default Page: It works
   Outlinks: 2
     outlink: toUrl: http://localhost/icons/ubuntu-logo.png anchor: Ubuntu Logo
     outlink: toUrl: http://localhost/manual anchor: manual
   Content Metadata:
     Accept-Ranges = bytes
     Keep-Alive = timeout=5, max=100
     nutch.fetch.time = 1591696071739
     Server = Apache/2.4.41 (Ubuntu)
     ETag = "2aa6-59647cb960db3-gzip"
     Connection = Keep-Alive
     Vary = Accept-Encoding
     Last-Modified = Fri, 01 Nov 2019 12:06:26 GMT
     Date = Tue, 09 Jun 2020 09:47:51 GMT
     Content-Type = text/html
   Parse Metadata:
     dc:title = Apache2 Ubuntu Default Page: It works
     Content-Encoding = UTF-8
     Content-Type-Hint = text/html; charset=UTF-8
     Content-Type = application/xhtml+xml; charset=UTF-8
   ```

> bq. I would also suggest making the output of Metadata::toString more readable(for instance by adding a newline before each new metadata value). It would have made this bug way easier to spot inside the output of the parsechecker.
