How about this solution?
In `defaults/main.yml`:
java_distribution_packages:
Debian: [ 'openjdk-7', 'java-stuff' ]
RefHat: [ 'java-runtime-7', 'other-stuff' ]
And then, in `tasks/main.yml`:
- {{ ansible_pkg_mgr }}: name={{ item }} state=latest
witn_items: java_distribution_packages[ansible_os_family]
I think that should work fine and let you override
java_distribution_packages in inventory.
