Custom Log Handler using HTTP PUT Method and creates loop

i working on a Java Webservice. We want to build our own Custom Log Service on Bluemix. To use the log service i created a custom Log handler.

The log handler builds the request in the publish method and then try to send via http put method the log to the log service.

url = new URL(REQUEST_URL);         
connection = (HttpsURLConnection) url.openConnection();
//Content type
connection.setRequestProperty("Content-type", "application/json");
// Request Method
connection.setRequestMethod("PUT");
// return parameter
connection.setRequestProperty("Accept", "application/json");

if (body != null) {
  String length = Integer.toString(body.length());
  connection.setRequestProperty("Content-Length", length);
  connection.setDoOutput(true);
  connection.getOutputStream().write(body.getBytes("UTF8"));
}   

But if i use the level FINE or FINEST the HTTPURLConnection logs too and builds a inifinite loop.
