FYI, I tried switching to use proguard but I couldn't find a way to make
proguard rename the packages but keep the original class names :(
but you can use it to strip unused static methods and then use jarjar
to rename the packages (see patch below) - though it would be cool
if we could get jarjar to do all of this...
the final guice jar after proguard'ing and jarjar'ing is ~600k
