SUN DESCRIBES REAL-TIME JAVA INTENT.
Sun Microsystems Inc says "real-time Java" is the wrong
way to talk about Java and real-time. Instead, it insists on
"real-time extensions to the Java platform." It claims that
this isn't mere semantic hair-splitting and says: "That the
end product be purely an extension is seen by us as fundamental."
To that end Sun says the real-time extension it is working on will
provide a set of low-level primitives out of which real-time systems can be built. It plans to come up with a set of very general primitives
or building blocks upon which Sun or others might build higher-level
abstractions. By real-time it means a system where timeliness is a part
of the system's behavioral requirements. It says a first version
of the spec will be targeted at uniprocessor systems. It has divided
the work into two parts. One deals with tightening the specification
of the behavior of the underlying virtual machine. The second details
new real-time APIs. It's not clear whether these goals dovetail or
overlay with the work of the Sun - IBM led real-time expert group
created under Sun's new community development process to extend
the Java platform.
