body: <p>I am new to power mock,</p>
  
  <p>In my program I am using <code>org.asynchttpclient.AsyncHttpClient</code> for HTTP request.</p>
  
  <p>I want to Mock that request using power mock,</p>
  
  <p>But It showing Error </p>
  
  <pre><code>"Caused by: java.security.NoSuchAlgorithmException: class configured 
      for SSLContext: sun.security.ssl.SSLContextImpl$TLSContext not a SSLContext"
  </code></pre>
  
  <p>I found something like :</p>
  
  <pre><code>@PowerMockIgnore({ "org.apache.http.conn.ssl.*", 
                     "javax.net.ssl.*",
                     "javax.crypto.*"            
                  })
  </code></pre>
  
  <p>But when I am adding this it show  <code>NullPointerException</code>.</p>
