title: Javac doesn't complain on not-catching exception (Runtime Exception)
body: <p>i have this in a class:</p>
  
  <pre><code>/* parses a Value out of a String */
  public static int parseValue(final String text) throws NumberFormatException {
  
      String cleanedValue = text.replace("-", "").replace(",", ".");
      return Math.round(Float.parseFloat(cleanedValue) * 100);
  }
  </code></pre>
  
  <p>For some reason javac doesn't complain that i don't catch the NumberFormatException in the calling code.</p>
  
  <p>Can someone tell me why that is?</p>
