JEP 401 EA release

[Dan Smith]

We're happy to report an implementation milestone: an updated EA release of Value Classes and Objects with all core functionality and optimizations implemented. We'll spend the next few months on stabilization and code review as we work towards a preview release in the JDK.

Binaries of the EA can be downloaded here:
