title: Mockito: How to match any enum parameter
body: <p>I have this method declared like this</p>
  
  <p><code>private Long doThings(MyEnum enum, Long otherParam);</code>
  and this enum</p>
  
  <pre><code>public enum MyEnum{
    VAL_A,
    VAL_B,
    VAL_C
  }
  </code></pre>
  
  <p>Question: How do I mock <code>doThings()</code> calls?
  I cannot match any <code>MyEnum</code>.</p>
  
  <p>The following doesn't work:</p>
  
  <pre><code>Mockito.when(object.doThings(Matchers.any(), Matchers.anyLong()))
          .thenReturn(123L);
  </code></pre>
