Nexus index not correct for Netty

Apologies if I have missed off any important details, please let me know what other information I need to provide and I will do glady. I initially raised a question on the Netty forum and was asked to raise an issue here by Trustin Lee.

Text from Forum Post...

I'm trying to point a local Nexus installation at JBoss so I can use Netty in a project I'm working on. However if I point my local Nexus to (i.e. add a repository and add it to the collection of Public repositories)...

http://repository.jboss.org/nexus/content/groups/public/

...it won't seem to find 3.2.4.FINAL.

Browsing the remote server from my Nexus shows the latest 3.2.4.FINAL jar file. However, browsing the index only shows up to 3.2.2.FINAL and even then only *-sources files are shown. In fact the latest one to show a "final release" is 3.1.5.GA.
