A C++ Native Interface for Interpreted JVMs

This paper describes JuNI++, a C++ native interface for interpreted Java Virtual Machines. While JuNI++ was initially designed in order to integrate the RTSJ implementation jRate with Juice, a virtual machine for small footprint environments, its engineering and performance advantages outlived the initial goal. The main contribution of this paper is to show how a C++ based native interface can fully and efficiently support the Java mapping in interpreted environments without requiring any cooperation from the C++ compiler.
