      People who are reading this forum might be interested to know that, today,
      Sun released the General Availability (GA) version of Java Real-Time System
      (Java RTS) 2.2, and that free evaluation versions are available for downloading:

      # [http://java.sun.com/javase/technologies/realtime/rts/]

      When you select a Java RTS 2.2 eval through the latter link, the download link
      will be sent to you by e-mail after you fill out and submit a quick survey. As part
      of the download process, you'll also need to agree to the terms of a click-through
      evaluation e-license -- an academic license for evaluators at any educational
      institutions and a 90-day license for any other evaluators.

      The supported platforms for Java RTS 2.2 are:

      # Solaris10 (SPARC, x86), Update 6 and 7
