When you reset, you cannot reset the log level for a particular logger. It
will reset the log levels for all loggers which are changed during runtime. So
if you call reset, it will reset the log level of ROOT to INFO, and the
particular logger to the log level when the runnable starts. If it was null
initially, its log level will be following the ROOT log level, INFO
