title: Could not initialize class twitter4j.TwitterFactory cause by NoClassDefFoundError
body: <p>I know the problem is <code>NoClassDefFoundError</code> when I build <code>TwitterFactory</code> form <code>ConfigurationBuilder</code> like this from RMI call:</p>
  
  <pre><code>    ConfigurationBuilder cb = new ConfigurationBuilder().setHttpProxyHost("58.215.173.23").setHttpProxyPort(8580).setOAuthConsumerKey("18aVBaTUUx5Axh1WgBe7w").setOAuthConsumerSecret("RhE83B9RML060mfMT2FVpD0O6V7wZxZnax1RCA3Y4");
      TwitterFactory tf = new TwitterFactory(cb.build());
      twitter = tf.getInstance();
  </code></pre>
  
  <p>But the debugger did't tells me what class is missing.I even cannot catch this exception,it just goes wrong.</p>
  
  <p>I got those information by add breakpoint at <code>ConfigurationBuilder cb = new ...</code>,and it stops at </p>
  
  <pre><code>public InvocationTargetException(Throwable target) {
      super((Throwable)null);  // Here
      this.target = target;
  }
  </code></pre>
  
  <p>in <code>InvocationTargetException</code> class, and I cannot get stacktrace also.</p>
  
  <p>Please help me to find out what is probably missing or I did something wrong.</p>
