<blockquote style="margin: 10px 0 0 0; border-left: 1px solid #cccccc; color: #707070; margin-left: 19px; padding: 10px 20px">
<p style="margin: 10px 0 0 0; margin-top: 0">We assume that developers who rely on Nashorn have had enough notice about its proposed removal to make alternative arrangements. The deprecation-for-removal of Nashorn in JDK 11 was confirmed in June 2018, causing the proposed removal to be flagged at every use of the <tt>jdk.nashorn.*</tt> API and the <tt>jjs</tt> tool in JDK 11, 12, and 13. During this period, no set of credible developers expressed a clear desire to maintain Nashorn in JDK 14 and beyond.</p>
</blockquote> <p style="margin: 10px 0 0 0">Given that this is about long term maintenance, I speculate that the intention here is to target this change to Java 15, 16 or 17 at the latest, so that there's no maintenance required after the next LTS version is released (Java 17, 21.9 LTS).</p> <p style="margin: 10px 0 0 0">It's still not obvious to me what "make alternative arrangements" means in practice, though. Rhino (the back to the future option) and GraalVM appear to be what people are suggesting.</p> <p style="margin: 10px 0 0 0">If Nashorn is removed in Java 15 or 16, it's not a big deal for us except to the extent that we want to test there, and if people want to deploy on them we won't support and it's their problem.</p> <p style="margin: 10px 0 0 0">Java 17 is where this becomes an issue. I assume that we will want to support our current version under Java 17 whether or not we move to a Java 17 platform right away.</p> </td>
