It's called the Javali Project. That link is in Portugeese, but here's the project leader, Bruno Souza, talking about it over at LXER.Com.
big in Brazil. (No, seriously, it is.) Brazil's voting machines run on an implementation of Java. The government of Brazil is becoming dependent upon it.
And that's why there is a sense of urgency about open source Java in Brazil. As Souza notes:
How can we guarantee that we'll have a compatible implementation of Java if (for example) a resolution from the US Administration forbids Sun to do business with Brazil? How can we base our development in a technology with such possibility? The only way to guarantee that longevity is if we have an international, open source community that can guarantee that.
Souza wants Sun to get involved in the discussion, and join some of the various projects working on a true open source Java.
Take the time to read his note, and bring some of the discussion back here. (If anyone can translate the Javali site, pass me a link.)
