Package: jruby Version: 9.1.17.0-3 Severity: grave Dear maintainers,
It seems jruby fails to run without declaring the DEBIAN_DISABLE_RUBYGEMS_INTEGRATION environment variable: jruby -e "puts 'Hello World'" WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by jnr.posix.JavaLibCHelper$ReflectiveAccess to method sun.nio.ch.SelChImpl.getFD() WARNING: Please consider reporting this to the maintainers of jnr.posix.JavaLibCHelper$ReflectiveAccess WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations WARNING: All illegal access operations will be denied in a future release NameError: undefined method `default_specifications_dir' for class `#<Class:0x24bdb479>' singleton class at /usr/lib/ruby/vendor_ruby/rubygems/defaults/operating_system.rb:84 <main> at /usr/lib/ruby/vendor_ruby/rubygems/defaults/operating_system.rb:58 require at org/jruby/RubyKernel.java:956 <main> at /usr/share/jruby/lib/ruby/stdlib/rubygems.rb:1 require at org/jruby/RubyKernel.java:956 <main> at /usr/share/jruby/lib/ruby/stdlib/rubygems.rb:1347 load at org/jruby/RubyKernel.java:974 <main> at uri:classloader:/jruby/kernel/gem_prelude.rb:1 Any value for DEBIAN_DISABLE_RUBYGEMS_INTEGRATION makes it work again: DEBIAN_DISABLE_RUBYGEMS_INTEGRATION=hamburger jruby -e "puts 'Hello World'" Hello World Talking with Antonio Terceiro, it seems the underlying problem comes from the current jruby version in Debian bundling an old version of rubygems, that isn't compatible with the code in /usr/lib/ruby/vendor_ruby/rubygems/defaults/operating_system.rb. Setting DEBIAN_DISABLE_RUBYGEMS_INTEGRATION seems like a cheap trick, as ruby gems in debian are 2.7 compatible, and our jruby is 2.3 compatible. Really, jruby shouldn't load gems from /usr/lib/ruby/vendor_ruby (but I'll open another bug about this). -- ⢀⣴⠾⠻⢶⣦⠀ ⣾⠁⢠⠒⠀⣿⡁ Louis-Philippe Véronneau ⢿⡄⠘⠷⠚⠋ po...@debian.org / veronneau.org ⠈⠳⣄
