title: Java: suppress warning "X is marked unstable"
body: <p>I am using the <code>com.google.common.net.MediaType</code> class from the <a href="https://github.com/google/guava" rel="noreferrer">Google Guava</a> library and it is marked as <code>@Beta</code>. I'd like to suppress warnings that this is marked as unstable.</p>
  <p>What's the <code>@SuppressWarnings</code> key do I need to use?</p>
