jar-dependencies cannot be updated out-of-band from jruby #7262
Description
I want to make feature improvements to jar-dependencies, but when I install the updated gem into my system, bundler will refuse to load it because the default gem has already been installed. I've determined that the problem is that the rubygems/defaults/jruby.rb requires a file from jar-dependencies extremely early in the boot process of any jruby process in order to hook into the rubygems install process. I plan on resolving this and sending PRs for both jruby and jar-dependencies, but want a tracking ticket first since it spans both projects.
Environment Information
jruby 9.3.1.0 (2.6.8) 2021-10-13 2e01e7199d OpenJDK 64-Bit Server VM 11.0.15+10-Ubuntu-0ubuntu0.22.04.1 on 11.0.15+10-Ubuntu-0ubuntu0.22.04.1 [linux-x86_64]Linux opennuc 5.15.0-37-generic #39-Ubuntu SMP Wed Jun 1 19:16:45 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
Expected Behavior
Gemfile:
gem "jar-dependencies", "~> 1.0" # installed manually locally; no actual code changes required other than the change in version number
Running bundle console should boot without error.
Actual Behavior
cody@opennuc:~/test$ bundle console
[DEPRECATED] bundle console will be replaced by `bin/console` generated by `bundle gem <name>`
[DEPRECATED] This Gemfile does not include an explicit global source. Not using an explicit global source may result in a different lockfile being generated depending on the gems you have installed locally before bundler is run. Instead, define a global source in your Gemfile like this: source "https://rubygems.org".
Resolving dependencies...
Gem::LoadError: You have already activated jar-dependencies 0.4.1, but your Gemfile requires jar-dependencies 1.0.0. Since jar-dependencies is a default gem, you can either remove your dependency on it or try updating to a newer version of bundler that supports jar-dependencies as a default gem.
