We have with 90% probablity decided that moving forward we will be using Mercurial for source control for our upcoming open source releases. The effort over at Sun has been very influential in this decision.
We are also considering switching to Mercurial from Subversion for internal development, but we have not yet reached a final decision on that.
In an effort to get our developers here in love with Mercurial I am doing a small amount of work on the Mercurial Eclipse plugin. Namely, the current version does not currently support remembering usernames and passwords for push and pull locations. I am attempting to improve that situation a bit.
