Java RADIUS Client Libraries

I’m interested in what Java RADIUS client libraries are available and actively supported.

This question is similar to What (good) Java RADIUS server libraries are out there?; however, I’m interested in Java RADIUS client libraries, as opposed to server libraries.

There are a number of server libraries, client libraries not written in Java, and immature/incomplete libraries and forks, so the only potential candidates I’ve encountered so far are the following:

• AXL RADIUS Client API – Not free/open source
• JRadius – Doesn’t appear to be actively maintained, last release January 2011, minimal community activity
• JRadiusClient – Minimal documentation/support, last updated 2004
• TinyRadius – Doesn’t appear to be actively maintained, last release February 2010, minimal community activity

Are there other libraries missing from my list?

I’d also be interested to know if anyone is actively consuming any of the libraries from the above list or has any experience/recommendations.
