bittorrent client: ttorrent doesn't work

Question

I want to start simple download using saved .torrent file on ("/sdcard/file.torrent").
I've tried ttorrent, because it's most simple bittorrent client.
ttorrent on github.com So I've tried this code, but had errors...

String filePath = "/sdcard/file.torrent";
String downPath = "/sdcard/A";                  

Client client = new Client (
    InetAddress.getLocalHost(),
    SharedTorrent.fromFile(
    new File(filePath),
    new File(downPath)
    )
);

client.setMaxDownloadRate(0.0);
client.setMaxUploadRate(0.0);           
client.download();
client.share(0);         
client.waitForCompletion();

Log:

Answer 1

Problem was in apache-commons lib. I used 1.8 (latest version), but for this ttorrent client 1.2 version is needed.

client.setMaxDownloadRate(0.0);
0.0 set no limit for download speed. But download speed is to low, Android uTorrent has much more.
