JRuby 10.0.0.0 Released

The JRuby community is pleased to announce the release of JRuby 10.0.0.0.

JRuby 10 is finally here! We've jumped to Ruby 3.4 compatibility and Java 21 minimum to bring you the best Ruby on JVM experience possible. We are confident this is the most compatible and stable major release we've ever had.

Our blog post on JRuby 10 provides a high-level overview of the major changes, with some additional details below. We will update the blog post with additional detailed articles over the coming weeks: https://blog.jruby.org/2025/04/jruby-10-part-1-whats-new

As with any "dot zero" release, we are planning a series of quick updates to address any last-minute issues that snuck into the release. Please file bugs for any issues you see while testing JRuby 10.0: https://github.com/jruby/jruby/issues

Contributors

The JRuby core team today includes Charles Oliver Nutter (@headius), Thomas Enebo (@enebo), and Karol Bucek (@kares). Over the past year we have been honored to accept contributions from many other developers, and JRuby 10 would not be as stable or complete without their help:

[@andsel], [@mrnoname1000], [@ahorek], [@evaniainbrooks], [@edipofederle], [@ccutrer], [@danini-the-panini], [@ntkme], [@andrykonchin], [@mohamedhafez], [@jsvd], [@jpcamara], [@mullermp], [@ikaronen-relex], [@jimtng], [@ryannevell], [@eregon], [@moste00], [@sk757a]

Ruby Compatibility

  • Ruby compatibility has been updated to Ruby 3.4. We consider this release equivalent to Ruby 3.4.2.
  • Most features of Ruby 3.2, 3.3, 3.4 are complete, but some are still in progress. See our checklists based on CRuby's release notes: Ruby 3.2, Ruby 3.3, Ruby 3.4
  • Except where a more recent gem was available or a library is unsupported by JRuby, we have included the same standard libraries as Ruby 3.4.

Java 21

After nearly a decade of supporting Java 8, the JRuby team decided it's time for us to move to a more modern version of Java. The new requirement of Java 21 will allow us to take advantage of many features that were impossible to utilize while simultaneously supporting Java 8:

  • On-by-default optimization using InvokeDynamic, which has significantly improved since Java 8.
  • Support for thousands of Fibers using the lightweight virtual thread support from Project Loom.
  • Fast native function calling and native memory management using Project Panama.
  • Greatly improved startup time using Application Class Data Store, enabled by default by our launcher executables.
  • Easier access to post-Java 21 features like the Ahead-of-time compiler cache in Project Leyden.

Upgrading to JRuby 10

This release marks a big leap forward for JRuby users, and we are standing by to help with your transition from JRuby 9.x or migration from CRuby. Support services are available to help migrate your critical applications. Many existing users trust JRuby Support by Headius Enterprises to keep their applications in peak condition and to prepare for future updates.

JRuby 9.4.11.0 Released

The JRuby community is pleased to announce the release of JRuby 9.4.11.0.

JRuby 9.4.11.x targets Ruby 3.1 compatibility. This release fixes two critical bugs in JRuby 9.4.10.0 and we recommend users skip that version when upgrading.

Thank you to our contributors this release, you help keep JRuby moving forward!

Critical Fixes

  • Fixed an issue where Mutex lock acquisition may leave the Mutex locked if an asynchronous Thread interrupt happens at the same time. #8585, #8586
  • Fixed a memory leak where singleton classes would leave behind bookkeeping objects that accumulated over time. #8591, #8598

Standard Library

  • rubygems been updated to version 3.6.3 to fix an incompatibility with bundler 2.6. #8590, #8596

JRuby 9.4.10.0 Released

The JRuby community is pleased to announce the release of JRuby 9.4.10.0.

JRuby 9.4.x targets Ruby 3.1 compatibility.

Thank you to our contributors this release, you help keep JRuby moving forward!

Ruby Compatibility

  • Fixed a NegativeArraySizeException crash parsing heredocs. #8355, #8557
  • Users can now opt into Ruby 3.3 behavior for NoMethodError and NameError that no longer inspects the target object. This inspect frequently led to memory issues. Specify JRuby flag -XnameError.inspect.object=false or JVM property jruby.nameError.inspect.object=false to disable the inspect call. #216, #8384, #8538
  • Implemented the missing Process.argv0 method, used by recent Bundler releases. #8568, #8570

Standard Library

  • The jar-dependencies gem, responsible for fetching jar file dependencies of Ruby gems, can now be updated independently of JRuby. #7262, #8488, #8502
  • An upcoming release of jar-dependencies, will fix issues sourcing jar dependencies in container deployments (partially fixed previously by an updated ruby-maven-libs gem). #7059, #8366
  • The psych gem is updated to version 5.2.3, including a fix for YAML aliases from SnakeYAML-Engine version 2.9. #8352, #8575
  • The reline gem is updated to 0.5.12. #8481

Java Integration

  • Only JVM classes imported from the same classloader hierarchy as JRuby will be bound to constants in JRuby's package hierarchy. #8156
  • Implementing a Java interface no longer leads to constant redefinition warnings. #8349, #8503
  • Precompiled Ruby scripts now properly prepare optimized homogeneous case/when statements. Previously they would deserialize incorrectly and garble the branches. #8421, #8424

Performance and Usability

  • Additional runtime data structures are eagerly cleared when tearing down a JRuby runtime, aiding GC. #8343, #8566
  • The JRuby shell-based launcher script now properly handles JRuby installed in a path with spaces. #8441, #8442
  • The Class#subclasses method has been optimized to eliminate it as a bottleneck in complex ActiveRecord STI queries. #8457, #8462
  • Integer multiplication operations that overflow outside of int64 range have been optimized to eliminate heavy exception raises. #8516, #8523
