Abstract

Despite Java's initial promise of providing a reliable and cost-effective platform-independent environment, the language appears to be unfavourable in the area of high-integrity systems and real-time systems.To address this issue, the language environment must provide not only a well-defined specification or subset, but also a complete environment with appropriate analysis tools. This paper describes an architecturally neutral real-time frame-work, which is proposed by the HIJA project, for safety critical systems with analysis tools. The goal of this paper is to present an overview of hard real-time profile and report on its current status. An avionic application is selected to experiment with the ANRT framework and the SCJ profile is also illustrated.
