title: Checkstyle "Method Not Designed For Extension" error being incorrectly issued?
body: <p>I'm using Checkstyle and am getting an error about this method:</p>
  
  <pre><code>public final String getAdmitCodeStatus() {
      return admitCodeStatus;
  }
  </code></pre>
  
  <p>Here's the error I get:</p>
  
  <blockquote>
    <p>Method 'getAdmitCodeStatus' is not designed for extension - needs to be abstract, final, or empty.</p>
  </blockquote>
  
  <p>How is that method not compliant? Is there something I'm doing wrong that Checkstyle would bark at me about this method?</p>
