Use of String.valueOf() and String.format("... %s", ...) is pointless

[Jason Dillon]

I've found a few places, that I happened to bump into while debugging, that do 
stuff like:

<snip>
        throw new IllegalArgumentException(String
            .format("Cannot create default factory for class: %s", 
String.valueOf(clazz)));
</snip>

This is complexly pointless use of String.valueOf(), as this is exactly what 
the "%s" token will do.  So its just wasting a method call, inflating the 
byte-code and cluttering up the source.
