Announcing: valhalla-spec-experts group

[Brian Goetz]

It's time to take the next step in Valhalla's evolution.  Accordingly, I've created the valhalla-spec-experts list, which will be the precursor to an eventual JCP Expert Group, and will operate under the JCP-friendly ToU.  This list is publicly archived in the obvious place, and the initial membership includes both corporate participation (Oracle, IBM, Red Hat, Jetbrains, Google) and individuals from the OpenJDK community.

As was the case when we formed the Lambda experts list, the role of valhalla-dev should now revert to its intended purpose, which is to discuss the *implementation* of Valhalla in OpenJDK.  Examples of appropriate discussion topics for valhalla-dev include:

- Bug reports
- Code review comments
- Test cases
- Build or porting problems
- Migration experiences for your own code

What we are trying to avoid is: having design discussions play out concurrently in multiple places with differing sets of players.  So please, we ask that you exercise restraint in commenting on active EG discussions -- as design decisions start to converge, we'll announce them here, and of course the primary place for implementation will remain the valhalla repositories.

Please remember that EG discussions often happen at a different pace than in other open-source projects.  Days can go by without a response, but this doesn't mean that the EG is not thinking about it, doesn't care, or is "stumped".  Often it simply means the EG members are working privately (or with their teams) to figure out what their position is, and will respond when they've thought about it more.  So, please let those discussions play out.
