The goal of Project Threeten was to integrate the JSR 310 Date and Time API Implementation into JDK 8. This project is sponsored by the Core Libraries Group.

The integration of JSR 310 into JDK 8 is complete and development finished. All feature additions will be considered for JDK 9 and bug fixes are to be evaluated for JDK 8 update releases.

Issues should be reported using the Java Bug Database, component: core-libs, subcomponent: java.time.

The Project Threeten Repository is no longer in use and has been removed. Fixes for issues are being integrated into the OpenJDK repository.
