title: Why are protected variables not allowed by default in Checkstyle?
body: <p>I get a lot of warnings in eclipse like these:</p>
  
  <blockquote>
    <p>Variable 'myVariable' must be private and have accessor methods.</p>
  </blockquote>
  
  <p>I think I get them because I didn't set <a href="http://checkstyle.sourceforge.net/config_design.html" rel="noreferrer">protectedAllowed</a> manually to true in eclipse. But why is it set to false by default? Shouldn't I use protected attributes?</p>
