I really hate how completely clueless people on hn are about java. This is not, and has not been an issue for many many years in Java and even the most junior of developers know how to avoid it. But oh no, go and rust is alwaayssss the solution sure.

Can you provide any examples or evidence of Java apps that prove this?

Because in my experience as of 2026, Java programs are consistently among the most painful or unpleasant to interact with.

IntelliJ IDEA is reasonably fast, but of course its hard to make a big desktop app in java be fast.

Crac / aot cache / ready now all can address this. Not even considering native aot. Multiple low latency trading systems across market markers, hedge funds and ibs prove this. But people just want to compare it to building a cli tool in go or rust.

But like can you provide an actual example of an application?

This seems like the key. HN is definitely biased towards simpler, smaller tools. (And that's not a bad thing!). The most compelling JVM stories I hear are all from much larger scale enterprise settings.

Kafka being a good example. It's very good at what it does, but painful to manage and usually not worth the pain for anyone who's not in a mega enterprise.

Because in real life, real world applications software is large, long running and needs to be bulletproof. Clis are not powering the world's infrastructure via piped bash scripts. It really baffles me what people actually do as software engineers on here with some of the nonsense that gets thrown around.

Ah, but let's port rust to the JVM!

But hey the sensationalist comment you originally posted gets your lots of upvotes…

I suppose they should be using rust yeah?

Should just use javafx or swing. Take a leaf out of intellij which while it as it's own performance problems (although not from the fact of the ui framework) has a fantastic ui across Mac / windows / nix

Java swing is way underrated despite being very complex. It baffles me why this just sort of withered on the vine.

(I was a swing developer for several years)

The web sucked all the oxygen out of the room.

It really was Oracle’s fault – they neglected deployment for too long. Deploying Java applications was simply too painful, and neither JLink nor JPackage existed.

Non-native UI widgets, non-native runtime, non-native language

I can’t tell if this word salad is sarcasm or genuine.

From the suggestions it looks like sarcasm, but you never can tell these days

This is hn, where unless something is written in rust or zig usually, people will hate on it. They would rather pump a cli tool than any software of sizable scale.

I love Rust. I love Haskell even more. I’m a big fan of Scheme. But anyone who “hates” on Java is just revealing a lack of understanding of what’s important in professional software development.

Java is a bad language for this compared to go? Is this legitimate advice on a serious programming blog. Pretty unbelievable honestly.

Wasteful? It's for entertainment on YouTube...what a nonsense take.

Maybe read to the end of the comment.

Not surviving more than 2 weeks in a QF role because of kdb, and then suggesting they should rewrite everything to LISP is one of the more HN level recidivous comments I think I have ever seen.

My Audi from 2018 has car play for free... this is absurd....

Anyone know if there's a good way to allow vial / qmk like customizations with a mac keyboard? I use things like auto shift on my custom splits, but would like to have some similar features on my mac keyboard.
