I think my question is, do most Java developers really know what goes outside of their window? Every language has a good story for web apps these days. The web is ubiquitous. You can write in Phoenix, Cowboy, Rails, Sinatra, Express, "net/http", Django, Laravel, Flask, Rocket... Java is literally middle of the pack at best. So that's not a compelling reason to use Java. So then we have to look at the rest of Java. Is there anything else in there that would make it better for web dev than a simple Go/Ruby/Python/Javascript/Rust/Elixir app? No? Ok, then let's not use Java. Java excels at being mediocre at everything, but the best at nothing.
