title: Java documentation -- missing methods?
body: <p>The method <code>init()</code> of <a href="http://docs.oracle.com/javase/8/docs/api/java/lang/Thread.html" rel="nofollow"><code>Thread</code></a> isn't in the Java documentation.</p>
  
  <p>Neither is <code>addUnstarted()</code> of <a href="http://docs.oracle.com/javase/7/docs/api/java/lang/ThreadGroup.html" rel="nofollow"><code>ThreadGroup</code></a>. </p>
  
  <p>What am I missing ???</p>
