title: Mockito.any returns null
body: <p>I am trying to mock a static method with parameters like this :</p>
  
  <pre><code>Mockito.when(StaticClass.staticMethod(Mockito.any(A.class), 
                                        Mockito.any(B.class), SomeEnum.FOO))
         .thenReturn(true);
  </code></pre>
  
  <p>I have added the following annotations :</p>
  
  <pre><code>@RunWith(PowerMockRunner.class)
  @PowerMockRunnerDelegate(Parameterized.class)
  @PrepareForTest({StaticClass.class, A.class, B.class})
  </code></pre>
  
  <p>But Mockito.any always returns <code>null</code>. Why ?</p>
