You've maybe missed the key point of GWT. It's definitely not to get around weird browser issues. The point of GWT is to create your complex business logic in Java (which Java is very good for), and then share that business logic across your server, web and mobile platforms. You can do the same with Javascript, but Java is (imo) better designed and suited to that task. Typescript is a closer alternative, but Java just plain has better tooling and server runtimes, and Typescript is compile-to-js in the same way Java with GWT is. That said, polymer with GWT is really nice and works as well as most web things. Stuff like Angular has so many problems of it's own that it's just plain false to say GWT is obsolete when it actually solves some of the problems Angular still has.
