Multiverse is a Java based Software Transactional Memory implementation I have worked on for the last half year and I made a lot of progress and gained a lot of new insights. But there is too much to do for me alone and I would really like have some people on the project to learn from/teach things to/have fun with. So if you are interested in joining the community, have experience with concurrency control/instrumentation or would like to know a hell of a lot more about it, please send an email to alarmnummer at gmail.com.
