---------------------------------------
Ok, after hours of looking at Log4j2 apidocs I realised that I was not
instantiating the LoggerConfig object properly.
Instead of:
LoggerConfig loggerConfig = LoggerConfig.createLogger("false", Level.ERROR,
"logger", "com.*", refs, null, config, null);
The loggerConfig object should be created like:
LoggerConfig loggerConfig = LoggerConfig.createLogger("false", Level.ERROR,
"logger", "true", refs, null, config, null);
Please note that the fourth param to be passed is "includeLocation", and it has
to be set to "true" for Reflection to kick in and the classname to be printed.
>From the APIdoc:
includeLocation - whether location should be passed downstream
Maybe the documentation for the parameter could be made clearer, but for now, I
think I am satisfied. So, marking this question as Resolved.
