alt Hacker NewsIt did used to be required. Older Java versions performed pretty terrible. However, Java 17+ completely fixed that. Even the heaviest modded setups run buttery smooth, even on older versions which are not well optimized.

It was more like Minecraft code was horrible, than anything else.
Creating objects like crazy, range for in hot paths, not caring about data representation, chosen algorithms,....
JIT and GC were already doing heroic efforts.
Yet, it settled Notch for life, which is something to take into account in the usual question regarding which technical stack for games.

It really wasn't and was always dubious.
A lot of the advice, for example, suggested using CMS. Which has been a terrible garbage collector almost since it was added to the JVM. When G1GC landed in 8, that was the correct GC to select for minecraft. Even the parallel collector would have been a better option than CMS in a lot of cases (sub 4gb heaps).
It was placebo. People wanted there to be SOMETHING that made things better so they reached for the billion different flags on the JVM (rather than fixing the underlying code). I've seen the same sort of mentality professionally and it's basically always been wrong.
