title: ReplaceAll and &quot; doesn't replace
body: <p>Can anyone point me out how the first if works and the second doesn't? I'm puzzled why the second if-clause isn't working. I'd like to get a hint, thanks.</p>
  
  <pre><code>String msg = o.getTweet();
          if (msg.indexOf("&amp;amp;") &gt; 0) {
              msg = msg.replaceAll("&amp;amp;", "&amp;");// vervangt &amp;amp; door &amp;
          }
          if (msg.indexOf("&amp;quot;") &gt; 0) {
              msg = msg.replaceAll("&amp;quot;", "aa"); //vervangt &amp;quot; door "
          }
