Hi Joe, > Who will be seriously impacted by the removal of Java 11 and what was your plan for upgrading to Java 17?
> > thoughts? I would support moving the minimum Java version to 17 if it wasn’t for the fact that Nashorn will be removed. Nashorn is already deprecated in Java 11, and was then fully removed in Java 15. I understand GraalVM is intended to be its successor, however this has not yet been integrated into NiFi and I’ve been unable to satisfactorily integrate it myself to date. In my NiFi usage, I make heavy use of the JavaScript engine in ExecuteScript and InvokeScriptedProcessor processors. To take advantage of GraalVM supporting later ECMAScript versions than Nashorn, I have been attempting to use GraalVM as the JavaScript Engine for NiFi with limited success. Further details have been provided in JIRA ticket NIFI-6229 [1] and I’d welcome any assistance in trying to finalise GraalVM support, but otherwise I’d consider the loss of Nashorn to be a potential blocker to adopting Java 17.
