b2fJ is distributed under MOZILLA PUBLIC LICENSE Version 1.0.
b2fJ is based on the leJOS project which is also distributed under MPL 1.0. At present, b2fJ shares most of its code with leJOX RCX JVM and jtool library, being mainly a port of leJOS under 8-bit architectures (most notably the Commodore 64). Java class library is taken from leJOS NXJ class library, with minor adaptations and additions from OpenJDK (see below).
leJOS is a tiny Java Virtual Machine targeting different Lego Mindstorms (RCX, NXJ & EV3); the project has many contributors, among them, Brian Bagnall, Jürgen Stuber and Paul Andrews.
leJOS was originally based on TinyVM by Jose H. Solorzano.
