Anyone who wants to dip their toe into JRuby contribution could start by looking at excluded ruby/json tests. A big one would be to implement ResumableParser, a json 3.x feature that never made it into the JRuby backend. Help wanted!

Audit excluded tests on JRuby and address differences · Issue #1123 · ruby/json
Several tests still explicitly exclude JRuby and do not run against the Java extension. We should reexamine these and fix as many differences with the C extension as possible. $ git grep -e "RUBY_E...

Exciting levels of activity in the JRuby repo lately! Heavily agent-driven, but our agent-focused docs and our policy of "you must understand your PR" has improved quality immensely. Feels like the early 2010s! Big improvements in fiber scheduling and async. Jump in and help!

Here's a nasty NIO gotcha: passing a large heap buffer to a blocking channel will copy the entire buffer to native, even if the write only consumes a small part of it. Subsequent writes will repeatedly copy everything left. Set a limit to only copy reasonably-sized chunks:

Cap heap buffer writes at 2MB per call by sampokuokkanen · Pull Request #9896 · jruby/jruby

I've seen things you people wouldn't believe. A 10k Sinatra controller, monkey patched abandoned ORM projects, JRuby.
All those moments will be lost in time as AI rewrites them.
All those moments will be lost in time as AI rewrites them.
I once inherited a python system that handled about $100m in ARR. It was a single Django class that was 25k lines long and had zero tests or docs that always called out to MySQL and postgres via fork+exec rather than actually using those client libraries
Agents turn out mediocre code, but I really don't think some people comprehend the horrors humans made before. I inherited an ETL pipeline that was a single 3k line python script/god class with control flow managed by adding, modifying, *and removing* properties. No arguments to be found.

Bring the jruby-rack 2.0 news. Half the room probably assumes JRuby means javax servlets and a 2014 Tomcat, and the Jakarta switch is the thing that unblocks deploys to current app servers.

I'd still like to have a better understanding of the exploits and confirm that JRuby would be unaffected. I don't think folks unfamiliar with the JVM understand how well this stuff has been designed for sandboxing and security.
