Validating Java for Safety-Critical Applications

Submitted by Jean-Marie Dautelle 2005-09-08 Java 14 Comments

"With the real-time extensions, Java can now be used for safety critical systems. It is therefore primordial to be able to guarantee that virtual machine implementations not only conform to the Real-Time Specification for Java (RTSJ) but also that efficiency and predictability is up to a certain standard. With these objectives in mind, we developed and maintained a test suite (.pdf) which addresses conformance as well as performance."
