Heyas, I've built up a Java API for the JSON RPC. It's a small api that facilitates access to the JSON RPC for Java apps, removing the need for knowing field names, parsing json, etc. It's also built in such a way that it is useful even as the spec changes, so that older versions remain useful, etc.
It can be found here:

Perhaps it could be added to the Add-Ons (resources.php) page?
New Java RPC API
