An internally used class for reporting internal messages generated by SLF4J itself, typically during initialization.

Internal reporting is performed by calling the debug(String), info(String), warn(String) (String)} error(String) (String)} and error(String, Throwable) methods.

See SLF4J_INTERNAL_VERBOSITY_KEY and SLF4J_INTERNAL_REPORT_STREAM_KEY for configuration options.

Note that this system is independent of the logging back-end in use.
