Its really exciting for this possibility. On the other hand, i am really convinced at this time that Javascript is a better language specially with ES6+, and that the node runtime is a better environment in terms of ease of use (developer ergonomics), performance, the fact that its thread safe (at the application level) by design and modular (via CommonJs).

I hope this does not mean in a few years that we are running Angular inside Websphere, but it might be the case.

And this is the Java issue, there is already a POC -> https://github.com/angular/universal/issues/280
