This article, the first in a five-part series on real-time Java, describes the key challenges to using the Java language to develop systems that meet real-time performance requirements.
Standard Java provides no guarantees for thread scheduling or thread priorities. An application that must respond to events in a well-defined time has no way to ensure that another low-priority thread won't get scheduled in front of a high-priority thread.

This partitioning would increase the overhead of these events and make communication between the events far more challenging.
