It was however completely rewritten in C++ when they needed to port it to more constrained platforms, every mobile and console version uses the C++ codebase while PC has both versions in parallel. If you ever intend to release your game on multiple platforms then Minecraft isn't an example to follow unless you're up for starting over from scratch at some point.

A side effect from specific platforms not allowing Java, and Microsoft buying Mojang.

Notch surely isn't sorry for having coded it in Java.

It worked out for Notch, sure, but most indie devs don't get the luxury of only considering console ports after they're already set for life from initially only releasing on PC. Planning for cross-platform from the start is table stakes, especially now the Switch has become just as if not more of a popular platform for indie games than PC is.

Most indie devs already strike gold if they manage one platform at all.

Too much is wasted on what language, or engine to use, instead of what actually make as a game.

And even when everything is done right, it is a drop in the ocean of daily released titles.

If anything using Java made it extremely moddable and is IMO part of the reason why it became a success.

Bad performance did delay one of the big new-biome-type releases in the Java version.
