coldfusion-out.log rotation not working ColdFusion 11

As I encountered a problem with the coldfusion-out.log rotation process I tried to change the value of the parameters maxOutFileBackup and maxOutLogSize in the neo-logging.xml file and restart the ColdFusion service.

The new parameters are not systematically taken into account and I could have coldfusion-out.log bigger than the max size defined in the xml file.

Content of the deployed neo-logging.xml:
