Is Java augmented with the RTSJ a better real-time systems implementation technology than Ada 95?

Abstract

This paper argues that Java (augmented by version 1.1 of the Real-Time Specification) will become superior to Ada 95 as a real-time systems implementation technology-once efficient and full implementations of version 1.1 become available. This is because the RTSJ will have an integrated set of mechanisms for representing the characteristics of real-time activities and a framework from within which those activities can be scheduled. Ada 95, in contrast, has a set of orthogonal low-level mechanisms which are invisible to the scheduler. Ada must, therefore, rise to the challenge and enhance its real-time support.
