connection timeout

[stalexxx]

Funny bug that i've discovered, when mistakenly set timeout to 10 milliseconds

the bug in this code

void fill(URLConnection anUrlConnection) throws IOException {
urlConnection = anUrlConnection;
try {
inputStream = anUrlConnection.getInputStream();
} catch (IOException e) {
// Per http://docs.oracle.com/javase/1.5.0/docs/guide/net/http-keepalive.html
// (comparable documentation exists for later java versions)
// if an HttpURLConnection was used clear the errorStream and close it
// so that keep alive can keep doing its work
if (anUrlConnection instanceof HttpURLConnection) {
HttpURLConnection conn = (HttpURLConnection) anUrlConnection;
InputStream es = new BufferedInputStream(conn.getErrorStream());

            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            // read the response body
            byte[] buf = new byte[1024];
            int read = -1;
            while ((read = es.read(buf)) > 0) {
                baos.write(buf, 0, read);
            }

            // close the errorstream
            es.close();

            throw new IOException("Error while reading from " + conn.getRequestMethod() + ": [" + conn.getResponseCode() + "] "
                    + conn.getResponseMessage() + "\n" + new String(baos.toByteArray(), "UTF-8"), e);
        } else {
            throw e;
        }
    }
}

we are trying to read output while stream is already closed by urlConnections so never reaching throw section

Thank you. I'll have a look
