@headius Can you review this?

[headius]

This change is safe and works on all JRuby versions. From JRuby 9.3 forward this require is needed to expose some JRuby-specific utility functions.

We have now another error. Is this related?

JRuby previously only shipped the extension and parser.rb because the rest of the source was licensed under something GPL-ish. That license has changed and parser.rb expects the rest of the gem to be present. I've fixed this by committing the rest of the racc library files for #6125.

We would prefer to source those files from the gem, but that will require @hsbt or someone else responsible for the racc gem to do a release.

[hsbt]

@headius I'm going to release the current master branch as racc-1.5.0 after cleaning-up the some of obsoleted files.

[hsbt]

@headius Done. https://github.com/ruby/racc/releases/tag/v1.5.0 and https://rubygems.org/gems/racc

[headius]

@hsbt Missed this until now. Thank you!
