I would propose another patch:

if (bufferCount > 0) {

The code I have used to test is the following:
+++
ServletOutputStream out = response.getOutputStream();
out.println("<br>Jean-Frederic uses ServletOutputStream<br>");
out.flush();

With the http connector it works without the output.flush()... But I have not
found why!
Any hints?
