I noticed that Real Time Java 2.2 was released back in September, seems to have come a long way from when I last looked at it. However, does anybody know of any real world uses, commercial or academic to date?

I offered some publicly-disclosed users of real-time Java in answer to another question; I'll reproduce here:
The Real-Time Specification for Java
now has several commercial-grade
implementations:
Sun/Oracle's JavaRTS (now unavailable, it appears Oracle has disbanded the JavaRTS team and made the product unavailable, without communicating publicly about it)- IBM's WebSphere
Real-Time
- Aonix PERC
- aicas JamaicaVM
- Apogee Aphelion
These products span the continuum from
compilation to native code (Aonix) to
J2ME (aicas, apogee), to full J2SE
(Sun, IBM). Most, if not all, have
seen deployments in small numbers of
safety- or mission-critical systems,
but momentum is building. Examples
include Eglin
AFB's space surveillance radar
modernization and the US Navy's
use of RTSJ in the DDG-1000/Zumwalt
destroyer. Sun also claims
deployment in the financial
transaction processing domain.
If you are interested in RTSJ, I
suggest Peter Dibble's Real-Time Platform Programming, or Professor
Wellings' Concurrent
and Real-Time Programming in Java.
On a related note, there is also work
underway to provide a Safety-Critical
profile for the Java programming
language, built as a subset of RTSJ.
Also, an expert group has formed to
explore a Distributed RTSJ DRTSJ,
but the work is stalled.
Not all of the above refers to Sun's JavaRTS or even RTSJ; several vendors have pursued their own proprietary path for real-time Java because they feel the RTSJ doesn't match their customers' needs.
Some additional users I'm aware of now include Army Future Combat Systems and several of the DARPA Urban Challenge contenders.
A version of Korean jet trainer T-50 will have a core application written in Real-time Java.
This Java application provides HUD, MFD diplays and all the core functions of the mission computer.
JamaicaVM from aicas is ported to indigenously developed mission computer.
Flight test is scheduled at the 4th quarter of 2010.
- Industrial Robot Control
- Embedded and Consumer Devices
- More Embedded Systems
Whole lot of other information on various systems in use (you would have to search for who is using those systems) both here and here.
Hope that helps!
Very realtime, but not all of the RTSJ standard is Ajile systems, they make hardware realtime java.
I used it on the M101 CROWS fire control computer. It's NOT the bit that failed in the video on youtube.
