Gmail is written in java and compiled to javascript via gwt. Doesn't count.

  Gmail's backend is written in Java. The frontend is written in Javascript, it has nothing to do with GWT.

    Sorry, you are incorrect. GWT writing javascript is the whole point. http://css.dzone.com/news/understanding-gwt-compiler http://css.dzone.com/news/understanding-gwt-compiler From the article: "The GWT compiler is really a Java source to JavaScript source translator."

      I don't think GWT is being used for gmail.
