[architm]

This is the stackTrace

Can you let me know why it is happening and implication of this in my application. The torrent is getting downloaded perfectly but want to root cause this issue before going forward.

EOFException means that the remote peer closed the connection.

Then is it good to log it as an error? It will try to find alternative peers then?

There are some other errors as well which i am getting.

It seems that it is unable to announce completion of torrent. Am i missing something in setup?

[atomashpolskiy]

Nope, most probably trackers are unavailable for some reason

Appreciate your quick response!

There are some other issues like the way i am calling library is like this btClient.startAsync(state -> { if (state.getPiecesRemaining() == 0) { btClient.stop(); isCompleted = true; System.out.println("Successfully completed torrent task!"); } else { System.out.println("Waiting for the torrent download to complete!"); } }, 1000);

How can i get the list of files information that is getting downloaded from my application? Basically after download is complete i want to process those files.

Any example would also work.

[architm]

Never mind got the example.
