FWIW, AFIAK:
it can also be noted that it does matter which class you pick, like 
generally you want the class and resource file to be in the same package 
and JAR and similar (the class basically telling the JVM where to look, 
otherwise the resource may not be found).

so, while a person can pick an arbitrary class, it may not necessarily 
find the resource.

so, generally, picking 'this' or similar makes sense, since normally a 
person will package the resources along with their own code.


or such...
