Hi Rafa,
We're getting the same error. I think it's because the creativecommons url
doesn't expose a content-length in the header. Possibly a recent change
because it seemed to be working for us last month.
I'm using the following (untested) workaround:
*Add to the imports...*
import java.io.BufferedReader;
import java.io.InputStreamReader;
*Replace everything in the try{} block with...*
URL url = new URL(url_string);
URLConnection connection = url.openConnection();
InputStream inputStream = connection.getInputStream();
BufferedReader reader = new BufferedReader(new
InputStreamReader(inputStream));
StringBuilder sb = new StringBuilder();
while ((line = reader.readLine()) != null)
sb.append(line);
return sb.toString().getBytes();
Instead of declaring a byte array upfront (which requires the length), I
read in the entire file and then output the byte array. As a side note, it
looks like version 1.8.0 catches the generic "Exception" and just swallows
the error.
Hope that helps,
