title: Add warning for missing @Override annotation for interface implementation in Eclipse
body: <p>In Eclipse 3.4.1 using JDK1.6.0_10 how can I activate a warning on a missing <code>@Override</code> annotation on a method that implements an interface method? </p>
  
  <p>In the Preferences window this option:</p>
  
  <blockquote>
    <p>Java > Compiler > Errors / Warnings >
    Annotations > Missing '@Override'
    annotation</p>
  </blockquote>
  
  <p>works fine for missing annotations on methods that override a superclass method, but it does nothing for interface methods.</p>
