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'"

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).
