March 30th, 2011
To upgrade from Rubygems v1.5.1 that comes with jRuby 1.6.0 simply do the following:
gem install rubygems-update -v 1.5.2 update_rubygems
Once you are on Rubygems 1.5.2 then you can update using:
gem update --system -v 1.x.x
If you need to downgrade:
gem install rubygems-update -v 1.5.1 gem uninstall rubygems-update -v 1.5.2 update_rubygems
