title: Null instanceof Object
body: <p>I was trying on something and I wrote this code,</p>
  
  <pre><code>boolean x = null instanceof Object;
  Object o = null; 
  boolean y = o instanceof Object;
  </code></pre>
  
  <p>It's is no surprise both returned false. What surprised me was, IntelliJ IDEA complained <code>y</code> is always <code>false</code> but didn't say anything about <code>x</code>. Does this imply something? </p>
