Specifically, the logging of class/method names without having to provide them. For example, in JDK 1.4 beta, you can do the following:
logger.config("Some message");
And it will provide the following info (I added the color for emphasis):
Jun 26, 2001 12:52:11 PM LogTest <init>
INFO:
Some message
As you can see, it picks up the class name and method (in this case, the constructor, represented by "<init>").
Note that .config is only used for example, as normally you would use logger.entering() / logger.exiting() (see bug ID #4474150).
This is very useful, since class names may change (though infrequent) and method names change (more frequent), plus, it allows for copy/paste of standard calls to every method:
logger.entering();
...
logger.exiting();
Also, if a class inherits from another class, it would be nice if it reported the actual class ("entering Apple" instead of the superclass "entering Fruit") without having to account for the differences.
Similarly, it would be nice if Category.getInstance() could add a no-arg constructor which would determine the class without having to add "MyClass.class" or "MyClass.class.getName()". I would make it additional, and not deprecate the existing, as you may want to setup global (public static) Category in a separate class.

On another note, just FYI, there are some typos in your documentation. In examples (and examples/doc-files), the *.lcf files spell "documentation" incorrectly (documenation).
