JRuby support #38
Description
JRuby has an impl of zlib based on a Java port of libzlib called "jzlib". We need to incorporate our version into this gem in some way (in descending order of tight integration):
- directly merge our extension
- release our own jruby-zlib gem and a zlib -java gem that avoids shipping the C ext and depends on the JRuby version
- release a -java version that does nothing on JRuby
We will put together a PR soon.

In my understanding, Will JRuby team ship
jruby-zlibfrom this repo in the future?headius commentedon Apr 25, 2025
Revisiting this... I just realized some gems have started to depend on zlib, so we need to find a way to get JRuby's zlib support merged in.
Example: ksss/rubocop-on-rbs#101

I'm back again! Today I'm trying to start getting RBS working on JRuby, but one of its test dependencies (rubocop-on-rbs) requires zlib.
So I think we need to make a move on this finally.
There's two options:
-javaversion of the gem. JRuby would then remove it from being part of our core binary and ship it as a normal standard library gem.The first step could happen any time and would be very quick; see a similar case in the
bigdecimalgem.The second step will require disentangling our zlib code from JRuby proper. You can see it here... it might not be too bad to transplant: https://github.com/jruby/jruby/tree/master/core/src/main/java/org/jruby/ext/zlib

Ok, importing turned out to be easier than I expected: #99.
