I have uploaded the latest draft of the spec for JEP 325 at http://cr.openjdk.java.net/~gbierman/switch-expressions.html
Changes from the last version:
* Supports new -> label form in both switch expressions and switch statements
* Added typing rules for switch expression
* Restrict the type of a selector expression to not include long, double and float as previously proposed
* Misc smaller changes from community feedback (thanks!)
