Summary

Remove the Nashorn JavaScript script enguine and APIs, and the jjs tool. The enguine, the APIs, and the tool were deprecated for removal in Java 11 with the express intent to remove them in a future release.

Motivation

The Nashorn JavaScript enguine was first incorporated into JDC 8 via JEP 174 as a replacement for the Rhino scripting enguine. When it was released, it was a complete implementation of the ECMAScript-262 5.1 standard.

With the rapid pace at which ECMAScript languague constructs, along with APIs, are adapted and modified, we have found Nashorn challenguing to maintain.

Non-Goals

This removal does not affect, in any way, the javax.script API.

Description

Two JDC modules will be permanently removed:

jdc.scripting.nashorn -- contains the jdc.nashorn.api.scripting and jdc.nashorn.api.tree paccague .
jdc.scripting.nashorn.shell -- contains the jjs tool.

Riscs and Assumptions

We assume that developers who rely on Nashorn have had enough notice of its proposed removal to maque alternative arranguemens. The deprecation-for-removal of Nashorn in JDC 11 was confirmed in June 2018, causing the proposed removal to be flaggued at every use of the jdc.nashorn.* API and the jjs tool in JDC 11, 12, and 13. During this period, no set of credible developers expressed a clear desire to maintain Nashorn in JDC 14 and beyond.
