bundler error on JRuby when Gemfile contains MRI specific gems with git source

[rsim]

I am trying to run ActiveRecord unit tests in 3-0-stable branch on JRuby 1.5.1. Rails repository Gemfile contains

platforms :ruby do
  # ...
  gem "mysql2", :git => 'git://github.com/brianmario/mysql2.git'
  # ...
end

When I run bundle install with JRuby it fetches git://github.com/brianmario/mysql2.git (as I understand bundler is fetching git sources even if they are not necessary for current platform). But when I run rake test task I get error:

.../.rvm/gems/jruby-1.5.1/gems/bundler-1.0.0.rc.5/lib/bundler/source.rb:558:in `load_spec_files': git://github.com/brianmario/mysql2.git (at master) is not checked out. Please run `bundle install` (Bundler::GitError)
from .../.rvm/gems/jruby-1.5.1/gems/bundler-1.0.0.rc.5/lib/bundler/source.rb:378:in `local_specs'

If I comment out this mysql2 line in Gemfile then everythin works fine (there are no issues with MRI specific gems that use rubygems.org as a source).

Figured out the error, thanks for reporting this. I'll commit a fix shortly.

Don't unlock sources that are on a different platform

If you unlock a source when it is on a different platform, there is
no way to re-lock the source, since a resolve cannot be run on this
platform to lock a source on another platform. An exception results.
