Hi Alan,

While removing the java.io.File import, I also questioned why I had 
java.io.IOException being imported. There were a couple of methods that 
declared it thrown, and the main method therefore had to catch it, but 
it turns out this was just copy/paste from the Settings.java test I used 
as a template, and is not actually needed. I removed the import, throws, 
and try/catch of IOException.

All the other issues mentioned by others have also been addressed. A new 
webrev can be found at:
