Description
As of 14.6, it looks as if the CMS fails to start when spring booth tries to parse a comma separated value of the log4j.configurationFile property, as it tries to parse it as a URL.
This is valid configuration, see the section 'Composite Configuration' or 'System Properties' here: https://logging.apache.org/log4j/2.x/manual/configuration.html
