title: ExpectedSystemExit is causing the error
body: <p>I'm using the library <a href="http://stefanbirkner.github.com/system-rules/" rel="nofollow">System Rules</a> to testing method that calls System.exit():</p>
  
  <pre><code>@Rule
  public final ExpectedSystemExit exit = ExpectedSystemExit.none();
  </code></pre>
  
  <p>Unfortunately, this piece of code is causing the error ...</p>
  
  <pre><code>initializationError caused an ERROR: org/junit/rules/TestRule
  </code></pre>
  
  <p>I'm using JUnit 4.7 and System Rules 1.2.0.</p>
