Description

@gettalong

I installed JRuby 10 to see if the test suite of HexaPDF runs successfully. Alas it crashes with an error.

Environment Information

  • JRuby version: jruby 10.0.0.0 (3.4.2) 2025-04-13 6ed59bc847 OpenJDK 64-Bit Server VM 21.0.6+7-Ubuntu-124.10.1 on 21.0.6+7-Ubuntu-124.10.1 +indy +jit [x86_64-linux]
  • Operating system and platform: Linux laptop 6.11.0-21-generic #21-Ubuntu SMP PREEMPT_DYNAMIC Wed Feb 19 16:50:40 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux

To reproduce

  1. git clone git@github.com:gettalong/hexapdf.git
  2. gem install cmdparse geom2d openssl strscan
  3. rake test

Expected Behavior

The test suite should run successfully.

Actual Behavior

The test suite fails with the following stack trace:
