I am trying to download a zip file but I get a Stream Closed Exception. When i use using swing gui it get this erro but if i use console there is no problem. Why do I get this exception? How can I fix it?

This is my code:

URLConnection conn = url.openConnection();
InputStream in = conn.getInputStream();
FileOutputStream out = new FileOutputStream(destination.getPath());
byte[] b = new byte[1024];
int count;

while ((count = in.read(b)) >= 0) {
    out.write(b, 0, count);
}
out.flush();
out.close();
in.close();
OptionPane.showMessageDialog(null, "Download is finished");
} catch (HttpUnauthorizedException e) {
    JOptionPane.showMessageDialog(null, "Proxy or Server Authentication Required");
} catch (IOException e) {
    System.out.println(e.getMessage());
}

this is stack trace

This exception usually means the connection was closed abruptly. I would look at the logs on the server to see if there was an error.

it can be due to JVM delays, It can be caused because of unix/linux operating system's random number generator. You should replace it with /dev/./urandom

This link has more details on it.

I solved it when removed this tag of Primefaces from my xhtml.
