We demonstrate how this challenge is being addressed in several Java-based systems. First, we lay out the design choices when implementing a process model in Java. Second, we compare the solutions that have been explored in several projects: Alta, K0, and the J-Kernel. Alta closely models the Fluke operating system; K0 is similar to a traditional monolithic kernel; and the J-Kernel resembles a microkernel-based system. We compare how these systems support resource control, and explore the tradeoffs between the various designs.
