      Description

      When the Log4j2CloudConfigLoggingSystem class runs the getStandardConfigLocations() method, if the log4j.configurationFile property is set, a StackTrace will be thrown. This happens because Arrays.asList() is used to convert the String[] to a list, but the list that is returned cannot be modified using any methods that would change the size of the array.
