    Description

      Running the following example with httpclient and httpcore 4.1.1 works fine.
      When using httpclient 4.2.1 + httpcore 4.2.2 or httpclient 4.2 + httpcore 4.2, I get "401 Unauthorized".

      The test source code

      try {
      httpclient.getCredentialsProvider().setCredentials(
      new AuthScope(targetHost.getHostName(), targetHost.getPort()),
      new UsernamePasswordCredentials("username", "password"));

      // Create AuthCache instance
      AuthCache authCache = new BasicAuthCache();
      // Generate BASIC scheme object and add it to the local
      // auth cache
      BasicScheme basicAuth = new BasicScheme();
      authCache.put(targetHost, basicAuth);

      // Add AuthCache to the execution context
      BasicHttpContext localcontext = new BasicHttpContext();
      localcontext.setAttribute(ClientContext.AUTH_CACHE, authCache);

      HttpGet httpget = new HttpGet("/vendor/apps/");

      System.out.println("executing request: " + httpget.getRequestLine());
      System.out.println("to target: " + targetHost);

      HttpResponse response = httpclient.execute(targetHost, httpget, localcontext);
      HttpEntity entity = response.getEntity();

      System.out.println("----------------------------------------");

      } finally

      { // When HttpClient instance is no longer needed, // shut down the connection manager to ensure // immediate deallocation of all system resources httpclient.getConnectionManager().shutdown(); }
      }

      }

      My current workaround is to manually add the authentication header:

      NEW WORKING example tested with 4.2+4.2 and client 4.2.1 and core 4.2.2

      // Add AuthCache to the execution context
      BasicHttpContext localcontext = new BasicHttpContext();

      HttpGet httpget = new HttpGet("https://api.heroku.com/vendor/apps/");
      httpget.addHeader(new BasicScheme().authenticate(usernamePasswordCredentials, httpget, localcontext));

      System.out.println("executing request: " + httpget.getRequestLine());

      }
