jruby-user - status of sonatypes gem repository for maven artifacts

What's the story is with sonatype's plan to host a gem repository for maven artifacts?
http://gems.sonatype.org isn't working
$ gem sources -a http://gems.sonatype.org
Error fetching http://gems.sonatype.org:
bad response Bad Gateway 502 (http://gems.sonatype.org/specs.4.8.gz)
headius has an article here: http://blog.headius.com/2010/01/busy-week-jruby-with-android-maven-rake.html
where he describes installing a maven artifcat as a gem like this:
gem install com.lowagie.itext-rtf
sonatype has an issue tracking this:
Add Ruby GEM support to Nexus: https://issues.sonatype.org/browse/NEXUS-3123
but it seems like it's only partly done
