Jainja JVM with Cosmopolitan Libc

Cosmopolitan Libc is a very interesting library which makes it possible to make an executable independent of the OS (but not of the architecture which must be x86)  
 
So I tried to compile Jainja JVM with this C library. It was pretty easy, apart from a few name collisions in headers.
 
There is now a JVM whose binary code works under Windows, Linux, xBSD and MacOS without recompilation !  

Cosmopolitan libc focuses on text-based user interfaces but AWT/Swing should work through X11 / TCP (not tested yet).

Jainja JVM on the Chrome Web Store

It was pretty easy to write a new graphical backend for Jainja using the Pepper Plugin API. So it's possible to write Java graphical user interfaces on NaCl now !

A demo is available on the Chrome Web Store.

HelenOS


This port was not too hard thanks to the POSIX compatibility layer of HelenOS. The lack of some math libraries was filled by fdlibm. A package for HelenOS is available here
