Design pattern for the adaptive scheduling of real-time tasks with multiple versions in RTSJ

This paper presents a design pattern of an adaptive scheduling based on the management of the tasks execution time, achieved through multiple versions of the tasks, applied to the real-time specification for Java. A structure of classes is used to facilitate the development of tasks, while allowing the independence of the application code from the code responsible for the adaptive control. The design pattern is described through UML diagrams and an example implementation is presented.
