English abstract:
Java is now considered as a language for the domain of safety critical
applications. A restricted version of the Real-Time Specification for Java (RTSJ)
is currently under development within the Java Specification Request (JSR) 302.
The application model follows the Ravenscar Ada approach with a fixed number
of threads during the mission phase. This static approach simplifies certification
against safety critical standards such as DO-178B. In this paper we extend this restrictive
model by mission modes. Mission modes are intended to cover different
modes of a real-time application during runtime without a complete restart. Mission
modes are still simpler to analyze with respect to WCET and schedulability
than the full dynamic RTSJ model. Furthermore our approach to thread stopping
during a mode change provides a clean coordination between the runtime system
and the application threads.
