“A real-time JVM can take advantage of real-time operating
system (RTOS) services to provide hard real-time capabilities, or
it can run on more conventional operating systems for applications
with softer real-time constraints. Some of the technologies used in
real-time Java come ‘for free’ when you switch to using a real-time
JVM. But to exploit certain features of real-time Java, some
changes to the application are required. These features are the
focus of this article.”
