A number of metadata field in the main pom.xml are out of date.
IssueManagement: protocol in now https
Mailing List: should point the to Google groups
Developers: either update or remove altogether
SCM: These point to trunk even on the branches and also will need changing to GIT when source moves.
Fixed most of this in rev 15323 in trunk. I'm going to bring the developers section up in the meeting in a few minutes.
Merged into 1.4.1 with commit 43d3f1e.
