Currently, one of the Fiddle tests fails with JRuby 10 (which passes with 9.4.12.0).

git clone https://github.com/ruby/fiddle.git
cd fiddle
bundle install
bundle exec rake test

Based on the error message, it seems like it may be an issue with JRuby (it's trying to convert a value to a long instead of an unsigned long), but haven't been able to identify the exact cause.

Environment Information

Provide at least:

• jruby 10.0.0.0 (3.4.2) 2025-04-13 6ed59bc OpenJDK 64-Bit Server VM 21.0.6 on 21.0.6 +indy +jit [arm64-darwin]
• macOS 15.4.1 arm64

Expected Behavior

All tests pass.

Actual Behavior

A single test failure:
