I have a method call which JRuby (9.4.2.0) seems to be incorrectly handling arguments for, raising "ArgumentError: wrong number of arguments (given 2, expected 1)", in particular circumstances. I haven't been able to come up with a standalone example to reproduce it but happens consistently with a library I maintain. A minimal script to trigger this, relying on that library:

require 'bundler/inline'
gemfile(install = true) do
  source 'https://rubygems.org'
  gem 'jsi', github: 'notEthan/jsi', ref: '5d1192f'
end

JSI::JSONSchemaOrgDraft07.schema.jsi_each_descendent_node { }

The commit introducing this is here: notEthan/jsi@5d1192f - the call from lib/jsi/schema/validation/ref.rb

Test workflow for that commit fails in JRuby: https://github.com/notEthan/jsi/actions/runs/5054298573/jobs/9069071917

I say 'particular circumstances' above - I haven't been successful coming up with a minimal, standalone script to reproduce because I can't tell what about the context triggers this. That same line of code is hit several times without erroring before the ArgumentError is raised (even with the exact same argument values). Changing the context slightly, e.g. removing or the jsi_memoize method (which caches the result of the block), or altering arguments to that method, causes the call to Schema::Ref.new to succeed without ArgumentError. I haven't been able to make sense of why, and this is as far as I have gotten with it.
