Ask HN: GWT for Mobile Web Apps?

I'm a developer working on a web application that runs on mobile devices. The idea has been floated by others on my team that we should switch to using GWT.

The biggest argument is that Java has compile-time type checking and better language constructs. Second, the backend is written in Java so there could be some code reuse.

The web app has completely custom UI elements with animation, has to support touch and remote control input, and limited CPU. It's not a vanilla enterprise or CRM application.

Any thoughts? Has anyone out there written a mobile web app using GWT?
