My concern is that when someone makes changes to the core, they have to make sure they didn't break the code, this includes all of the contrib modules, which _could_ mean that I need more than just 1.4 and 1.5 to build and test the core and contrib areas. I just think it could get out of hand. The system requirements document could get too complicated. I am all for moving to 1.5; I am not in favor of letting the contrib package range freely over whatever JVM version is available.
