Hi all!
I’m running Camunda on linux and using numerous JS script tasks. After one recent server update I was horrified by a warning:
Warning: Nashorn engine is planned to be removed from a future JDK release
Will there be any solution for this? Or I will have to rewrite 1K+ script tasks (30K+ lines of code) to groovy?
Hi @Denis_Nikolaev,
this warning is issued from the JVM of Java 11, NOT from the Camunda Engine itself.
You can find details about it here: https://openjdk.java.net/jeps/335.
Hope this helps, Ingo
Hi, Ingo!
Thanks for the reply, but my question was not, actually, about JDK: I’m wondering, if Camunda engine will support JS in scripting tasks some other way, when the Nashorn scripting engine is removed from JVM.
Hi Denis,
We have an open ticket for resolving the warning on Camunda side: CAM-11687
Best regards,
Yana
Hello, Yana! Yes, I’ve seen the ticket.
Once again, my question is not about suppressing the warning: it’s easily done with the flag during java startup.
-Dnashorn.args=--no-deprecation-warning
I’m wondering, whether you are going to do anything like, let’s say, embedding NodeJs into Camunda to provide JS functionality when the Nashorn engine is removed from openJDK. Or, maybe, using the GraalVM within the Camunda docker…
Guess, the answer is ‘No’ 
Hi @Denis_Nikolaev,
My hope is, that before the Java script engine is removed from the JDK, the Java community would offer some way to add it explicitly. Otherwise a lot of projects will run into trouble (not only Camunda related).
Let’s see how this will continue.
Cheers, Ingo
from this: https://bugs.openjdk.java.net/browse/JDK-8241749
It seems like its been removed for Java 15.
thanks for the heads up.
It seems to me that the GraalVM offers an alternative that could be included with additional dependency in POM: https://golb.hplar.ch/2020/04/java-javascript-engine.html
When I find some time, I will try it out.
Cheers, Ingo
Would be great if you could share any findings in https://jira.camunda.com/browse/CAM-12103.
Cheers,
Thorben
Hi All,
I tried with Java 11 (adopt jdk). I got below error

Welcome to the forum.
This is quite an old thread - so i think it’s best that you create a new topic for your question.
I’d also ask that you read the FAQ (paying particular attention to the style guide) so that you can make the question easier for everyone to answer. In the meantime i’m going to lock this topic
