The typical way of adding logging to a class involves a reference to the class itself:
private static final Logger kLogger = LoggerFactory.getLogger(MyClass.class);

Not all tooling catches renames and whatnot – I've had several occasions where the old class reference inadvertently came along for the ride and made for misleading logs.

I started putting this into a little utility class in my projects to prevent this and I think it would be a good addition to LoggerFactory. While the stacktrace calls might not be the cheapest, it's only hit during class initialization.

public static Logger getDefaultClassLogger()

{ return LoggerFactory.getLogger(Thread.currentThread().getStackTrace()[2].getClassName()); }
