> Exception is thrown at line 92 of class Log4j2CloudConfigLoggingSystem.
> Reason is pretty simple:
> {noformat}
>         String location = props.getStringProperty(ConfigurationFactory.CONFIGURATION_FILE_PROPERTY);
>         if (location != null) {
>             List<String> list = Arrays.asList(super.getStandardConfigLocations());
>             list.add(location);
>             locations = list.toArray(new String[0]);
>         }
> {noformat}
> Method {{Arrays.asList()}} returns *fixed size list*, so the next line call {{list.add(location);}} causes exception:
> java.lang.UnsupportedOperationException: null
