Yes, its closed. One point I didn't mention, is that it is Java 5 based source.

While being able to look at the source and see why particular pieces
of code are triggering particular language change proposals, its worth
pointing out that OSS is very different code.

OSS is typically library/framework code, closed source is typically
business logic. As shown in my figures, that can greatly affect the
kind of results you get. I'd also note that there is vastly more
closed source than open source. So, its the closed source code that
needs to be tackled by language changes.

(I'm not arguing that we shouldn't run it against OSS either! But I do
believe that closed source is in the end the primary interesting case)

BTW, I understand that James Gosling did similar analysis when
evaluating accessing lists/maps by array-like syntax.

The key is to obtain data points, which help Joe/Sun make decisions.

The tool took less than an hour total, but split over the four runs.
The other figures required some Eclipse searches, so the whole effort
took a little longer.
