Licensing
The primary component of GWT, the Java-to-JavaScript cross-compiler, is proprietary, binary-only software. The Java API libraries are open source software, distributed under the Apache License. The API libraries have essentially no value without the proprietary compiler. The (non-critical) hosted-mode browser is also under the proprietary license. GWT is provided free of charge.
Echo2 is open source software, licensed under the Mozilla Public License, and provided free of charge.
