title: Matchers.any() for null value in Mockito
body: <p>Suppose I am having this object <code>objectDemo</code> which calls to the method <code>objectDemoMethod</code> with 2 parameters <code>String</code> and <code>null</code>. Now I want to verify with Mockito that this method was called:</p>
  <pre><code>objectDemo.objectDemoMethod(&quot;SAMPLE_STRING&quot;, null);
  </code></pre>
  <p>I have written this:</p>
  <pre><code>Mockito.verify(objectDemo, Mockito.times(1)).objectDemoMethod(Matchers.any(String.class), null);
  </code></pre>
  <p>but it's giving an error:</p>
  <blockquote>
  <p>Invalid use of argument matchers for null value.</p>
  </blockquote>
  <p>Is there any another way to pass <code>null</code> value?</p>
