Installing latest jruby with ruby-install

[anquegi]

Environment Information

Provide at least: I try to install the latest jruby using ruby-install,

uname -a                                                                                                                                      
Linux toni6.6.34-1-MANJARO #1 SMP PREEMPT_DYNAMIC Wed Jun 19 19:00:06 UTC 2024 x86_64 GNU/Linux

But it point that I need jdk 8 installed, and that's not needed how can I change this:

java -version                                                                                                                                      
openjdk version "17.0.11" 2024-04-16
OpenJDK Runtime Environment (build 17.0.11+9)
OpenJDK 64-Bit Server VM (build 17.0.11+9, mixed mode, sharing)

and when I try to install I get this:

JAVA_HOME=/usr/lib/jvm/default ruby-install jruby-9.4.6.0                                                                                                ✔

Which I thin the problem is with old openssl in java 8, so I want to know how to install jruby pointing the correct SDK and the correct version of openssl

JRuby should install and work just fine with any JDK 8 or higher, so I'm not sure why you needed JDK 8 specifically.

That exception class was removed in 2020 (ab35995e5bd60cb60bdff4d6c095882dac2a6292) and the last reference to it in jruby-openssl was removed in 2018 (jruby/jruby-openssl@153028d3e4ba4ae5291670c5f6a261d9e19b562c). You are on the right track suspecting an old jruby-openssl is conflicting with the newer JRuby.

You may have it installed somewhere globally, or it is being picked up by whatever libraries/specs/code you are running. I notice LogStash mentioned in your output.

Can you provide a step-by-step reproduction, perhaps with a repository we can clone to match your environment? It's hard to know why you are getting this mismatched environment based on the output you have provided.
