Adobe has open sourced the JavaScript engine in Flash under the auspices of the Mozilla Foundation. I don't think this is all of Flash, but I could be wrong abnout that. (I'm not a big Flash person.) Specifically, they are releasing
the ActionScript™ Virtual Machine, the powerful standards-based scripting language engine in Adobe® Flash® Player, to the Mozilla Foundation. Mozilla will host a new open source project, called Tamarin, to accelerate the development of this standards-based approach for creating rich and engaging Web applications.
The Tamarin project will implement the final version of the ECMAScript Edition 4 standard language, which Mozilla will use within the next generation of SpiderMonkey, the core JavaScript engine embedded in Firefox®, Mozilla’s free Web browser. As of today, developers working on SpiderMonkey will have access to the Tamarin code in the Mozilla CVS repository via the project page located at www.mozilla.org/projects/tamarin/. Contributions to the code will be managed by a governing body of developers from both Adobe and Mozilla.
This code is licensed under the same Mozilla tri-license (MPL/GPL/LGPL) as other Mozilla code. They even beat Java out the door. Isn't that ironic?
The Eclipse Project has released the Web Tools Platform 1.5.2. I've tried this out in the past, and found it to be a hideous mess; and probably a good case study in how not to design a GUI app. This is a bug fix release, but really what this project needs is to be taken out behind the barn and shot.
