It seems that JINI is pretty much an abandoned project. The latest release from the Jini.org site is from last year, and there has been no news since then.
JINI appears
From what I see the last Jini release actually was in October 2005 (Check here). What you maybe referring to is the news entry for the Rio project on the jini.org site I guess.
The wikipedia page on Jini tells us
Originally developed by Sun, responsibility for Jini is being transferred to Apache under the project name "River"
The latest release for Apache River (2.2.1) is from last year. There still seems to be some activity on the svn repository. So maybe not completely dead but also not very much alive too.
