title: Force protocol in Client using httpClient 4.3.6 on Java 6
body: <p>For some testing reason I need to force SSLv3 to be used by Client. SSLv3 is an accepted protocol in server. Tried to force by using SSLContextBuilder.useProtocol("SSLv3") as below: </p>
  
  <p>SSLContextBuilder initiated as below: </p>
  
  <pre><code>    SSLContextBuilder builder = SSLContexts.custom();
  
      SSLContext sslContext = builder.useProtocol("SSLv3").build();
  
      SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext, new X509HostnameVerifier() {
          @Override
          public void verify(String host, SSLSocket ssl) throws IOException {
          }
       ....
       ....);
      return sslsf;
  }
  </code></pre>
  
  <p>But the result in log shows handshaking always do in TLSv1:</p>
  
  <pre><code>....
  ....
  Allow legacy hello messages: true
  Is initial handshake: true
  Is secure renegotiation: false
  %% No cached client session
  *** ClientHello, TLSv1
  RandomCookie:  
  GMT: 1503650935 
  bytes = { 
  255, 
  ....
  ....
  </code></pre>
  
  <p>My understanding, client should request for the protocol that is defined whether server accept or not. In this case, I expect to see client should request to use SSLv3 not TLSv1.</p>
