I have no idea why the JRuby jobs are stuck.

I have pushed the missing bits for JRuby and rebased on current master.

Additional changes from previous review:

• Rakefile tweaks to get paths set properly for JRuby, with the JRuby-specific wait.rb moved under ext/java/lib.
• Gemspec tweaks to include lib/io/wait.jar and the Java ext files in the gem

This addresses both of @ahorek's review comments. I also tested that the built gem can install and replace the builtin io/wait in JRuby.

So it is pretty close now.

Something is still not right with the JRuby builds.

is it missing a bundle exec before rake?

There are no dependencies for CRuby (dev or otherwise) so no bundling is done in any of the builds.

I will add the necessary bits for JRuby.

Looks like we have a winner!

This can be squashed during merge, or if preferred I can rewrite the commits to better reflect the changes I made.

Pinging maintainers... I believe this is ready to merge and is necessary for JRuby 9.4 to source io-wait (and the net/* libraries that use it) from the gems. High priority for JRuby 9.4 release in the next month or two.

I have updated this from master again. Is there anything else needed to merge?

The omitted test has been un-omitted, since that issue was fixed in JRuby 9.3.1.0 (current is 9.3.3.0).

I rebased this on master and it will merge now. I'm fine with merge commit or squashed.

I have addressed all review comments.

🎉

Thank you both!
