Janino is distributed under the terms of the New BSD License. I chose this license so that Janino will (hopefully) be useful in both free and proprietary projects. (In the past, JANINO was first licensed under the LGPL, and then under the Apache License.)
As of today, Janino is written and maintained entirely by Arno Unkrig and Matt Fowles. We are independent from SUN Microsystems Inc.
Janino was initially developed with JDK 1.2.2 and CVS on Linux. Meanwhile, support for JDK 1.2.2 was dropped, and we switched version control to SVN. Janino is tested against SUN JDK 1.3.1 and 1.6.0.
Janino should run on any operating system platform for which a JDK 1.3.1 or higher is available.
Janino now is a nearly complete JavaTM compiler. The focus is now on stabilization and adding the few language features that are still missing.
There's no special story behind the name. It begins with a "J", "janino.net" was still available, and it sounds similar to the name of a close relative of mine ;-)
