But it's also the reason for why these Apache projects systematically get displaced by better and faster C, C++, Rust or Go alternatives.

It would make sense for a highly succesful but stable java project to be replaced like that, but since I'm in the java world, it's usually replaced with another java project.

I could provide examples myself, but I'm not convinced it's about java vs c++ or go: hadoop, cassandra, zookeeper

As an outsider, Java looks like a language that can be very fast but it seems like certain idiomatic practices or patterns lead to over-engineered and thus sometimes also slow projects. The Factory<Factory<x>> joke comes to mind.

2010 called, it wants its Java jokes back.

Because once you have a base codebase in a particular language, it is silly to rewrite it in another, as ultimately language choice doesn't matter that much. But if you are going to rewrite stuff from scratch, Java is a horrible choice in the modern age.
