Steps to reproduce:
1. Install the CA on an Ubuntu 12.04+ system using the install scripts
2. Note failure to install.
Maven 2 does not work with new versions of Matterhorn, so we see a compilation failure when it tries to download one of the Jersey deps. Luckily, Ubuntu 12.04+ ship with a 'maven' package which (for some reason) installs Maven 3.0.4 which just works (since it understands what the Jersey project did to its pom files).
