 From a very quick glance, this looks like neither. printf (through the 
Formatter object) uses the classloader to find locale-specific files (so 
it can do proper formatting operations). Since the classloader is not 
initialized yet, it cant be used; creating a new one would lead to 
infinite recursion (since the new classloader would again try to 
initialize the Formatter object).
