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=falseor JVM propertyjruby.nameError.inspect.object=falseto disable the inspect call. #216, #8384, #8538 - Implemented the missing
Process.argv0method, 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#subclassesmethod 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
