title: ReflectionTestUtils not working with MockitoJunitRunner
body: <p>Need is to write test case for a service. 
  It initially uses value properties like :</p>
  
  <pre><code>@Value(#{"env.host"})
  private String host;
  </code></pre>
  
  <p>I came across ReflectionTestUtils.setField and tried the same as below,with cloudImpl class with InjectMocks annotation:</p>
  
  <pre><code>ReflectionTestUtils.setField(cloudImpl, "env.host", "localhost");
  </code></pre>
  
  <p>All i get is cannot find field "env.host" of type null in cloudImpl class. Could you please help figure out why ?</p>
