I've made it to day 2 of JavaOne. Currently I am sitting in the morning general session.
Yesterday was pretty busy. It started with the opening day general session which turned out to be a little bit of a zoo. Try to imagine 8000 people trying to filter into the same room at the same time. Needless to say there was quite a bit of waiting in line. Once we all sorted out though it turned out to be a good keynote to kick of the week.
