> The default log4j.properties has:
> log4j.rootLogger=DEBUG, CONSOLE
> where the console appender is only outputting INFO level and above.
> This is resulting in a large number of debug logs being generated, which are 
> all filtered out by the console appender (by default there are no other 
> appenders used)
> We need to change the default rootLogger to INFO level, which will resolve 
> this issue.
> Users are free to change this of course -- most likely they would only do 
> this when debugging an issue, and would not want to run in DEBUG in 
> production (again, they are free to choose).
