title: Unmatched closing ')' in replaceFirst
body: <p>I have this code to remove first closing ')' from an input String:</p>
  
  <pre><code> if (campo.indexOf(")") &gt;= 0){
          campo = campo.replaceFirst(")", "");
      }
  </code></pre>
  
  <p>At runtime, I recieve this error</p>
  
  <blockquote>
    <p>Unmatched closing ')'</p>
  </blockquote>
  
  <p>What's wrong with that replace? I checked that there is a ')' before even trying to replace.</p>
