How much overhead does Category.getInstance cost? Is it measureable?
I preffer Mark's method.
I also wrapped up NDC and ConfigureAndWatch as well.

I also created a wrapper for Category, but instead of always calling the
Category.getInstance() method, I instantiate the wrapper class and it stores
a reference to the Category object. Then uses the reference in implementing
the various methods. Doing it this way means that we create an object for
each Category (we only create one instance, like log4j), but we don't pass
the class everywhere.
Advantages? Disadvantages?

I created a wrapper class around Category. You're going to create your
debug(), error(), fatal(), info(), and warn() methods in here. You'll
also need a fully-qualified-classname of the wrapper class. So here's
an example:
class Logger {
private static final String FQCN = Logger.class.getName();
public static void debug(Class c, Object message) {
Category.getInstance(c).log(FQCN, Priority.DEBUG, message, null);
}
public static void debug(Class c, Object message, Throwable t) {
Category.getInstance(c).log(FQCN, Priority.DEBUG, message, t);
}
/* Continue wrapping all the others... */
};
