Swap Java and Go in text, then I buy it. Java is memory hungry monstrosity that runs on JVM and idiomatically uses piles of abstractions. I have exactly opposite experience, when rewriting a microservice from Jave to go reduced memory usage tenfold and sped up requests processing.
I don’t know why you keep getting downvoted, there’s no good code in all the universe written in a language that contains the letters j-a-v-a.
According to votes, hating Java is bad, but hating microservices is good.

Java’s biggest strength is that “the worst it can be” is not all that bad, and refactoring tools are quite powerful. Yes, it’s wordy and long-winded. Fine, I’d rather work with that than other people’s Bash scripts, say. And just because a lot of Java developers have no concept of what memory allocation means, and are happy to pull in hundreds of megabytes of dependencies to do something trivial, then allocate fucking shitloads of RAM for no reason doesn’t mean that you have to.

There is a difference in microservices between those set up by a sane architect:

  • clear data flow and pragmatic service requirements
  • documented responses and clear failure behaviour
  • pact server set up for validation in isolation
  • entire system can be set up with eg. a docker compose file for testing
  • simple deployment of updates into production and easy rollback

… and the CV-driven development kind by people who want to be able to ‘tick the boxes’ for their next career move:

  • let’s use Kubernetes, those guys earn a fortune
  • different pet language for every service
  • only failure mode is for the whole thing to freeze
  • deployment needs the whole team on standby and we’ll be firefighting for days after an update
  • graduate developers vibe coding every fucking thing and it getting merged on Claude’s approval only

We mostly do the second kind at my work; a nice Java monolith is bliss to work on in comparison. I can see why others would have bad things to say about them too.

Nothing in my message is about microservices. I don’t care about that fight. I just hate java.

I was referring another comment in the thread, sorry for confusion. The OP attacks both Go and microservices, although it’s no Gos fault in the story.

Also I just hate Java too, and OOP in general.
