This project aims at providing a free (GPL'd) Virtual Machine based on the Java Micro Edition specification. This Virtual Machine, Jelatine, is characterized by its highly efficient use of memory, as well as the ability to scale from 16 bit processors up, and to be ported on most architectures that support ANSI C.
The current release, Jelatine 0.8, features interpreted execution only, but the virtual machine is geared towards JIT compilation. The Jelatine package and its documentation can be found at the Sourceforge project page.
Jelatine is developed and maintained by Gabriele Svelto.
