We do this now with Java 1.5, Greg. Java RT 2.1 (64 bit) is compatible with Java 1.5. http://preview.tinyurl.com/2bpjqfh There would be no other test than works-with-Java-1.5. The simple answer is that if River does not call real-time threads and uses Java 1.5 there is no issue. There are other things that impact real-time but we can cover those.
