[jira] Created: (HARMONY-6521) [classlib][luni] HttpURLConnection.getResponseCode() hangs on incomplete chunked response

[classlib][luni] HttpURLConnection.getResponseCode() hangs on incomplete chunked response
-----------------------------------------------------------------------------------------

                 Key: HARMONY-6521
                 URL: https://issues.apache.org/jira/browse/HARMONY-6521
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
    Affects Versions: 6.0M2, 5.0M14
            Reporter: Mark Hindess
             Fix For: 6.0M3, 5.0M15


HttpURLConnection.getResponseCode() hangs when reading chunked responses because it eagerly tries to find the size of the first chunk.  It should read the chunk size lazily.  The RI doesn't hang.

import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.ServerSocket;
import java.net.URL;

public class HUCHang {
    public static void main(String[] args) throws Exception {
        ServerSocket server = new ServerSocket(0);
        URL u = new URL("http://"
                        + server.getInetAddress().getHostAddress()
                        + ":" + server.getLocalPort());
        HttpURLConnection uc = (HttpURLConnection)u.openConnection();
        uc.connect();
        OutputStream cos = server.accept().getOutputStream();
        String resp =
            "HTTP/1.1 200 OK\r\n"
            +"Content-Type: text/plain\r\n"
            +"Transfer-Encoding: chunked\r\n"
            +"\r\n"
            +"a"; // intentionally incomplete chunk size line
        cos.write(resp.getBytes());
        System.err.print("response code = \"");
        System.err.println(+ uc.getResponseCode() + "\"");
    }
}

Given that chunked responses are often used for (slow) streamed responses then matching behaviour makes sense.
