undefined method `parse' for JSON::Ext::Parser:Class #694

Closed mullermp closed 2 weeks ago

Something in json 2.8.0 or 2.7.6 breaks usage of AWS SDK for Ruby / JRuby 9.4 related to the json class.

undefined method `parse' for JSON::Ext::Parser:Class

This happens when doing require 'aws-sdk-dynamodb'

Example CI - https://github.com/aws/aws-sessionstore-dynamodb-ruby/actions/runs/11707818540/job/32608074498

I've confirmed pinning to 2.7.5 with JRuby solves the issue.

Looking.

I'm able to repro locally, somehow jruby is loading the jar that is bundled with JRuby instead of the one bundled in the gem:

>> $LOADED_FEATURES.grep(/json/)
=> 
["/Users/byroot/.gem/rubies/jruby-9.4.8.0/gems/json-2.8.0.1-java/lib/json/version.rb",
 "/Users/byroot/.gem/rubies/jruby-9.4.8.0/gems/json-2.8.0.1-java/lib/json/common.rb",
 "/opt/rubies/jruby-9.4.8.0/lib/ruby/stdlib/json/ext/parser.jar",
 "/opt/rubies/jruby-9.4.8.0/lib/ruby/stdlib/json/ext/generator.jar",
 "/Users/byroot/.gem/rubies/jruby-9.4.8.0/gems/json-2.8.0.1-java/lib/json/ext.rb",
 "/Users/byroot/.gem/rubies/jruby-9.4.8.0/gems/json-2.8.0.1-java/lib/json.rb"]

Digging more.

Fixed in 2.8.1. Thanks for the report.

@byroot The 2.8.0 gem should probably be yanked since the JRuby version is completely broken right now. Thanks for the quick fix!
