org.slf4j.impl.Log4jLoggerAdapter
public final class Log4jLoggerAdapter
A wrapper over org.apache.log4j.Logger in
conforming to the Logger interface.
Note that the logging levels mentioned in this class refer to those defined
in the
org.apache.log4j.Level class.
The TRACE level was introduced in log4j version 1.2.12. In order to avoid crashing the host application, in the case the log4j version in use predates 1.2.12, the TRACE level will be mapped as DEBUG. See also bug 68.

throws ObjectStreamException
This approach will work well if the desired ILoggerFactory is the one references by LoggerFactory. However, if the user manages its logger hierarchy through a different (non-static) mechanism, e.g. dependency injection, then this approach would be mostly counterproductive.
