Does Nashorn (org.openjdk.nashorn) have any support for Java 17?

[Greg Watts]

Dear Nashorn development team,

I am trying to run an ANT build of our product using
nashorn-core:15.1.1.jar with Java 17 (pre-release - build 27) and I get:

BUILD FAILED

So I was curious to know please if Nashorn will be supported in Java 17,
and if so, when you might anticipate that to be released (ballpark
estimate)?
