rubygems/rubygems#1685 didn't get into release so I added it manually like in bdb4a36
It looks like smth went wrong. I'll dig into it.
Ok, I reverted update to 2.6.7 because it breaks default behavior.
When I ran:
bin/jruby -S gem list --no-version |xargs bin/jruby -S gem uninstall -aI
it removed all default gems:
bin/jruby -S gem list
*** LOCAL GEMS ***
Apply patch from rubygems/rubygems#1685
Seems fine to let this bake on master. I'll file an issue for updating to a stock release before 184.108.40.206.
