Description
https://mail.openjdk.org/pipermail/leyden-dev/2024-July/000760.html

Note the command lines below. jruby specifies these options that are not supported (or sufficiently checked) by the optimizations in the Leyden EA release

    --add-opens=java.base/java.nio.channels=org.jruby.dist 
    --module-path=/xxxx/jruby-9.4.8.0/lib/jruby.jar 

=== reproduce ===
Download and unpack https://repo1.maven.org/maven2/org/jruby/jruby-dist/9.4.8.0/jruby-dist-9.4.8.0-bin.tar.gz

$ cd jruby-9.4.8.0
$ JAVA_HOME=/repo/leyden/build/linux-x64/images/jdk bin/jruby -J-XX:CacheDataStore=jruby.cds -e '10.times { org.jruby.Ruby.newInstance }'

Comments
The crash is no longer reproducible with Leyden/premain. I saw the following warning message: [0.001s][warning][cds] optimized module handling/full module graph: disabled due to incompatible property: jdk.module.addopens=java.base/java.io=org.jruby.dist Error occurred during initialization of VM AOT cache cannot be created because AOTClassLinking is enabled but full module graph is disabled The fix for JDK-8352003 allows --add-opens to be specified during creating and using of AOT cache. So closing it as a duplicate.

Problem: - ClassPreloader doesn't know how to handle classes in user-defined modules, so it just drops them from the preloading list - When --add-opens is specified, the CDS archive becomes unuseable Temporary work around: https://github.com/iklam/jdk/tree/work-around-8335735-jruby-crash-due-to-lack-of-module-support -> https://github.com/iklam/jdk/commit/d9287e9b01a991637bb2c86e7b0425c159cc08bf
