(master) rdoc test suite failing with Java::JavaLang::ArrayIndexOutOfBoundsException #8083
Description
The test suite for ruby/rdoc has been failing on JRuby master for the last two weeks or so. This suite passes with JRuby stable releases.
Environment Information
jruby 9.4.6.0-SNAPSHOT (3.1.4) 2024-01-22 7609e7b3ad OpenJDK 64-Bit Server VM 11.0.21+9 on 11.0.21+9 +jit [x86_64-linux]- github actions ubuntu-latest image
Last green test suite run was with jruby 9.4.6.0-SNAPSHOT (3.1.4) 2024-01-20 e43e3b56ed in https://github.com/ruby/rdoc/actions/runs/7613213302/job/20732599904.
First failing test suite run was with jruby 9.4.6.0-SNAPSHOT (3.1.4) 2024-01-22 7609e7b3ad in https://github.com/ruby/rdoc/actions/runs/7619307831/job/20752157542
Expected Behavior
I believe the test suite is valid and should pass.
Actual Behavior
See failure example at https://github.com/ruby/rdoc/actions/runs/7619307831/job/20752157542
