A real-time Java Virtual Machine with applications in avionics

摘要

A hoary falsehood about Java is that it is unsuitable for hard real-time applications, due to the need for garbage collection (GC). The Real-Time Specification for Java (RTSJ) that is now eight years old should have put this to rest, yet the falsehood still circulates in many circles. For this reason, the paper should be required reading for anyone who is interested in or involved in teaching real-time systems, especially to those interested in understanding RTSJ and what an implementation really looks like.
