I tend not to agree with most of your points, but it may be a matter of taste. I actually like Java (but I also see quite some overengineering in some places).

I don't see that. It's actually quite nice for my taste. I guess you don't like generics, but then you have to live without them, which also sucks.

What do you mean exactly? There are things like thymeleaf if you want SSR, otherwise you can put whatever SPA in front of it.

.. it's not hard to use Spring Security though

>Elixir/Phoenix/Ecto" - is there some devise like auth by now? I also like Elixir/Phoenix quite a lot, but it's nowhere near Rails/Springs level.
