Yes, but the free Java world goes forward, plethora of projects use generics -
and they require >= 1.5 (or any other feature of JDK 1.5).

Yes, but VM which is running maven is not the same as VM for which the code is
generated (note -source and -target options of javac).

You're missing the point: the official tree (gentoo-x86) will require >=1.5,
*but*: if you install JDK 1.4 (or any other version) you can still use it for
your own software (including maven, ant and so on).

Also like I said - more and more things require 1.5, which means that all things
depending on them also need to be >= 1.5. For example: new hessian requires >=
1.5, which means that mx4j needs also to be switched to 1.5, which means we have
to switch anything depending on mx4j, and so on.
