Component Root logger:

When a JBI component is installed, the framework creates a component root logger with the name "com.sun.jbi.<component-name>". By configuring this component root logger, all other component logger could be configured.

System root logger:

When Fuji framework starts up, it creates a system a root logger with the name "com.sun.jbi". This is the parent logger for all other runtime loggers and component loggers. By changing this logger's level, all other Fuji loggers (that were created with the default level - inherits from parent) can be configured automatically.
