title: issue at downloading torrents java
body: <p>I'm trying to build a java torrent downloader, based on <a href="https://github.com/mpetazzoni/ttorrent" rel="nofollow noreferrer">ttorrent</a> java library (link goes to docs and basic instructions).</p>
  
  <p>I followed the instructions listed in the javadoc , exactly as they are. When running the code, notthing appears to happen. No exceptions either. And obviously the file is not downloaded, I can't even see a ".part" file in my downloads folder. Stays at 0%.</p>
  
  <p>This is my code so far (compare it with the code in the docs).</p>
  
  <pre><code> Client client = new Client(
  
                       InetAddress.getLocalHost(),
  
                       SharedTorrent.fromFile(
                               new File(TORRENTPATH),
                               new File(MKPATH)));
  
               client.download();
               client.waitForCompletion();
  </code></pre>
  
  <p>I didn't find any better documentation of ttorrent than that one. What am I doing wrong? And of course, the torrent has seeds because I downloaded it before from another torrent manager.</p>
  
  <p><strong>UPDATE</strong>: Although nothing is downloaded, the download process appears to start but throws the following log message:</p>
