    OAuthAuthorization authorization = new OAuthAuthorization(ConfigurationContext.getInstance(), CONSUMER_KEY, CONSUMER_SECRET, accessToken);
    Twitter twitter = new TwitterFactory().getInstance(authorization);
    try {
        //twitter.updateStatus("Hello World!");

Go to your already created application (https://dev.twitter.com)
Check your application settings (> Application Type)
'Application Type' need to be one of Read, Write and Access direct messages. If not you can easily make an update.

(I tested your code in processing environment and it is working)

First of all , regenerate your acces token/secret and consumer key/secret. Then try this.

String consumerKey = "yourconsumerKey ";
       String consumerSecret = "yourconsumerSecret";
       String accessToken = "yourAccessToken";
       String accessSecret = "yourAccessSecret";

       ConfigurationBuilder cb = new ConfigurationBuilder();
       cb.setDebugEnabled(true)
           .setOAuthConsumerKey(consumerKey)
           .setOAuthConsumerSecret(consumerSecret)
           .setOAuthAccessToken(accessToken)
           .setOAuthAccessTokenSecret(accessSecret);

       try 
       {
          TwitterFactory factory = new TwitterFactory(cb.build());
          Twitter twitter = factory.getInstance();

          System.out.println(twitter.getScreenName());
          Status status = twitter.updateStatus(latestStatus);
          System.out.println("Successfully updated the status to [" + status.getText() + "].");
           }catch (TwitterException te) {
              te.printStackTrace();
              System.exit(-1);
           }

Statuscode 401 means you're not authorized

Check if your credentials are valid. If they are, maybe your application has not been validated by the user. See the examples on twitter4j site (point 7)
