Your HTTP client disconnected.

This could have a couple of reasons:

• Responding to the request took too long, the client gave up
• You responded with something the client did not understand
• The end-user actually cancelled the request
• A network error occurred
• ... probably more

You can fairly easily emulate the behavior:

URL url = new URL("http://example.com/path/to/the/file");

int numberOfBytesToRead = 200;

byte[] buffer = new byte[numberOfBytesToRead];
int numberOfBytesRead = url.openStream().read(buffer);
