Google Web Toolkit (GWT) performs inlining of javascript code, minifying and removing unused code, and some other optimizations which are also done by Google Closure Compiler. So I was wondering if Closure Compiler is in fact utilized in GWT or do they have two separate implementations? If so, then what is the restriction/reasoning for not reusing Google Closure Compiler in GWT?
Commit 10778: Closure JS hookup hooks GWT to the closure compiler.
Probably with GWT 2.5, at least behind the scenes, GWT may use the closure compiler.
