title: Findbugs issue with "Boxing/unboxing to parse a primitive" with Integer.valueOf(String)
body: <p>I have this piece of code:</p>
  
  <pre><code>public void someMethod(String id) {
     someOtherMethod(Integer.valueOf(id));
  }
  
  public void someOtherMethod(int id) {
     // do something with id
  }
  </code></pre>
  
  <p>And on that second line, Findbugs is throwing this exception:</p>
  
  <blockquote>
    <p>Boxing/unboxing to parse a primitive</p>
  </blockquote>
  
  <p>Why is Findbugs complaining about this when I'm simply calling Integer.valueOf() / how can I fix this?</p>
