This is how is was designed to work. Aether can do anything but the original implementation is simply a map of GAs with a version preference. If the GA is encountered then its version is overridden. This effectively gives you a target platform like mechanism but is intended to be controlled from the final application. Maven does not consider depMan at every level in the tree. It's a global map controlled from your project and its functionality is very limited in scope. You would need to do some relatively sophisticated conflict resolution to have every sub graph and its managed dependencies be reconciled with every other. Not that it can not be done but this certainly not how dependency management is implemented currently. This is not a bug, this is how the feature is implemented.
