I agree.
I don't know many people who have shit on Java more than I have, but I have been using it for a lot of stuff in the last year primarily because it has a gigantic standard library, to a point where I often don't even need to pull in any external dependencies. I don't love Oracle, but I suspect that at least if there's a security vulnerability in the JVM or GraalVM, they will likely want to fix it else they risk losing those cushy support contracts that no one actually uses.
I've even gotten to a point where I will write my own HTTP server with NIO (likely to be open sourced once I properly "genericize" it). Admittedly, this is more for pissy "I prefer my own shit" reasons, but there is an advantage of not pulling in a billion dependencies that I am not realistically going to actually audit. I know this is a hot take, but I genuinely really like NIO. For reasons unclear to me, I picked it up and understood it and was able to be pretty productive with it almost immediately.
I think a large standard library is a good middle ground. There's built in crypto stuff for the JVM, for example.
Obviously, a lot of projects do eventually require pulling in dependencies because I only have a finite amount of time, but I do try and minimize this now.
Do you really need to roll your own NIO HTTP server? You could just use Jetty with virtual threads (still uses NIO under the hood though) and enjoy the synchronous code style (same as Go)
