"Among the contentious open source projects that Oracle
inherited from Sun was the Hudson continuous integration
The Hudson project was forked into the Jenkins CI project, which
has continued to go its own path. Oracle hasn't given up on Hudson
though and has moved the project to the Eclipse Foundation to keep
the project, open and alive.
At JavaOne 2011 there are at least five sessions that will be
talking about Hudson, and a whole separate conference across the
street about Jenkins.
