title: Mockito gives UnfinishedVerificationException when it seems OK
body: <p>Mockito appears to be throwing an <code>UnfinishedVerificationException</code> when I think I've done everything correctly. Here's my partial test case:</p>
  
  <pre><code>HttpServletRequest req = mock(HttpServletRequest.class);
  when(req.getHeader("Authorization")).thenReturn("foo");
  
  HttpServletResponse res = mock(HttpServletResponse.class);
  
  classUnderTest.doMethod(req, res); // Use the mock
  
  verify(res, never());
  verify(req).setAttribute(anyString(), anyObject());
  </code></pre>
  
  <p>And here's the partial class and method:</p>
  
  <pre><code>class ClassUnderTest extends AnotherClass {
      @Override
      public String doMethod(ServletRequest req, ServletRequest res) {
          // etc.
          return "someString";
      }
  }
  </code></pre>
  
  <p>Ignoring the fact that you should never mock interfaces you don't own, why is Mockito giving me the following message?</p>
  
  <pre><code>org.mockito.exceptions.misusing.UnfinishedVerificationException: 
  Missing method call for verify(mock) here:
  -&gt; at (redacted)
  
  Example of correct verification:
      verify(mock).doSomething()
  
  Also, this error might show up because you verify either of: final/private/equals()/hashCode() methods.
  Those methods *cannot* be stubbed/verified.
