Our use case is actually quite simple so I think it would be easy to get functionality again, but would rather find something that will last more than a few years without heavy maintenance.

The JEP is a candidate, and they’re gathering feedback there. If there’s a lot of community feedback saying people use and depend on Nashorn, it’ll be taken into consideration. Lots of people have already chimed in on that thread already saying they rely on Nashorn. If you can re-post your below messages in that thread, it’d be the best. If you are not subscribed to jdk-dev, you can do so at <http://mail.openjdk.java.net/mailman/listinfo/jdk-dev <http://mail.openjdk.java.net/mailman/listinfo/jdk-dev>>.
