JaRTS: A Portable Implementation of Real-Time Core Extensions for Java

To implement real-time tasks in Java the Java Virtual Machine has to be enhanced by the ability to run threads in a predictable time and to access hardware directly. One approach is to provide a real-time add-on for standard Java Virtual Machines. Benefits of this approach are a better predictability, a better scalability and more flexibility.

In this paper JaRTS—an implementation of the Real-Time Core Extensions specification—is presented. Some implementation details are inspected and first results are shown.
