Implementing Java in Internet Appliances

A core component of many Internet Appliances is the Java Virtual Machine (JVM). The desired behavior of a JVM in an embedded device goes beyond the correct execution of Java programs. The JVM must operate robustly and predictably in the face of inevitable resource restrictions while minimizing interference with other native functionality inside the device. It must adapt smoothly to properties of device features, and show optimal performance under conditions pertaining to embedded devices. The purpose of this paper is to help the reader evaluate JVM products by pointing out critical areas in which Java Virtual Machines may differ.
