Review comment:
       So would we just make the class extend `UncheckedIOException` and leave everything throwing it as it is now? I personally don't like the way in the arguments it puts the exception first and the message second, I find this confusing as most other Java Exceptions do it the other way around. There is also the "magic" it performs to `String.format` things which again was a bit of a surprise and forced me to look into the internals which I rarely have to do with other Exception types I've used.
   
   You guys know a lot more about how this is used but since its an Unchecked Exception is API compatibility such an issue? Perhaps there is a defined set of classes where it needs to be kept but can be removed everywhere else?
