This will session of 2 parts. The first part will focus on getting the OpenJDK built. For this part of the session, bring your laptop and make sure that you have a copy of the OpenJDK source code downloaded. Also have a read of the OpenJDK build README and get as many of the dependencies downloaded as you can. The Internet connection at the conference it likely to be unreliable so don't rely on being able download during the day.
The second part will look at some deep and dark areas of Hotspot including class file loading/parsing and VM Intrinsics. I'll try to build some connections between the features and theory of hotspot and the code that implements them.
