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.
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.
