An update on Objects.newIdentity for Java 17: Roger did some work to put the feature together and get it reviewed.


However, while the implementation is straightforward, for libraries folks not deeply familiar with the Valhalla Project, the concept of a method that does the same thing as 'new Object()' did not seem particularly justified. I think they're especially uncomfortable with the idea of talking about creating an "identity" in a world in which all objects have identity.


So, not going to work out for this release. We made a bet that it would be a simple, noncontroversial matter to slip in an extra method, but it turns out to be a tougher sell than we thought.

Of course, as part of JEP 401, a feature like this will have the surrounding context, with things like the IdentityObject interface, so that it will make a lot more sense. We'll plan for that.
