title: Spring ReflectionTestUtils does not set static final field
body: <p>I have a static final field like this:</p>
  
  <pre><code>class SomeClass {
      static final String CONST = "oldValue";
  }
  </code></pre>
  
  <p>and i'm trying to change that field in test like this:</p>
  
  <pre><code>ReflectionTestUtils.setField(SomeClass.class, "CONST", "newValue");
  </code></pre>
  
  <p>but it doesn't work and says </p>
  
  <pre><code>java.lang.IllegalStateException: Could not access method: Can not set static final java.lang.String field
  </code></pre>
