Feel free to do whatever you want to with this code. It uses the google api, which you can find out about at http://www.google.com/apis/. You'll need to replace "GET YOUR OWN KEY" below with your own key...

I find that the instrumentation I do is generally fine, but subject to odd little quirks that some compilers (or other instrumentation tools) produce.
I only have the javac on Apple to work with and I *seem* to have complete coverage of what it produces, but I notice now and then that other compilers produce different byte code and that I sometimes mess up on this code because I've never seen it before.
So my question is: "Do we have a collection of class files that give wide coverage of all the possible orderings for byte codes?"
