Properti jaringan disetel untuk proxy SOCKS & Proxy.NO_PROXY tertentu

Tes sederhana untuk memaksa koneksi langsung ke toto.localhost.lan (yang disajikan di mesin lokal saya) ketika properti sistem dikonfigurasi untuk menggunakan proxy SOCKS.

package net.wetope.launcher.tests;

import java.net.URL;
import java.net.URLConnection;
import junit.framework.TestCase;

public class AppTest extends TestCase {

  public void testFile() {
    try {
      System.setProperty("socksProxyHost", "127.0.0.1");
      System.setProperty("socksProxyPort", "9999");

      URL url = new URL("http://toto.localhost.lan/");
      URLConnection conn = url.openConnection(java.net.Proxy.NO_PROXY);
      conn.getInputStream();
    } catch (Exception e) {
      e.printStackTrace();
      fail();
    }
  }
}

Tes ini menghasilkan:

Koneksi dicoba melalui proxy SOCKS meskipun saya menetapkan untuk menggunakan koneksi langsung.

Ada ide?

Terima kasih
