Ive updated the JBM 2 libs. I would recommend deleting your thirdparty dir.
I can probably reduce these again by removing commom-core and adding the individual libs, but since time is short I'll look at this after Beta.
Also, a few of the new libs are only at CR so these will need updating once A 5.1 is released.
Regarding Maven, if we have to support updating the old repos everytime we need new libs it might be worth while. Maven also lets you download specific jars from a project so it would make our distro smaller. We could still use Ant as the build just have a pom instead of a build-thirdparty.xml. Maybe after Beta.
