Jato VM

The JIT-only Java virtual machine that aims to support JVM specification version 2

Jato is an open source, JIT-only virtual machine for Java that aims to support the JVM specification version 2 including 1.5 amendments. It is not complete but you can run some Java applications with it on 32-bit x86 Linux machines. Jato uses Boehm GC as its garbage collector and GNU Classpath to provide essential Java run-time libraries. A port to the x86-64 architecture is currently ongoing.

How can I try it out?

Use the following command to clone the git repository:

  git clone git://github.com/penberg/jato.git

and then check out the README file for details how to compile and install Jato on your machine.
