We initially considered using GraalVM but had difficulty finding out
what jars should be included in Solr (or how to build those). We were
also not sure about the scripting features or compatibility with our
existing update scripts. Of course GraalVM would be a better alternative
since it is actively maintained.

Thanks for sharing this. I am a bit fuzzy on what the path forward to Java
21, no security manager, and continuing to be able support the Nashorn based
scripting libraries. My understanding is Nashorn is no longer in Java. The
github repo you mentioned doesn't seem super active but might work for us.
I also saw references to GraalVM, and
https://www.graalvm.org/latest/reference-manual/js/ScriptEngine/ implementation.
It will be interesting to see where we go with one of my favorite features of Solr, the
scriptingupdaterequestprocessor! I always think of it as "the tool I reach for when
I am in trouble in data processing ;-) ".
I would love more folks to be thinking about this path and discussiong (maybe
on the dev mailing list) there thoughts of where we go.

Hi Doss,
I had to include more jars. What worked for me was the following:
- Clone https://github.com/openjdk/nashorn and build with
```
cd make/nashorn
ant jar
```
- Copy the following generated jars to .../solr-9.7.0/lib/
.../nashorn/build/nashorn/dist/jjs.jar
.../nashorn/build/nashorn/dist/nashorn.jar
.../nashorn/build/nashorn/dependencies/asm-7.3.1.jar
.../nashorn/build/nashorn/dependencies/asm-analysis-7.3.1.jar
.../nashorn/build/nashorn/dependencies/asm-commons-7.3.1.jar
.../nashorn/build/nashorn/dependencies/asm-tree-7.3.1.jar
.../nashorn/build/nashorn/dependencies/asm-util-7.3.1.jar
You might also have to disable the Solr security manager by setting
`SOLR_SECURITY_MANAGER_ENABLED=false` in .../solr-9.7.0/bin/solr.in.sh. See
also
https://solr.apache.org/guide/solr/latest/upgrade-notes/major-changes-in-solr-9.html#security-3.
I hope that helps,
