Seems like an interesting effort. A developer is building an alternative Java-based backend to Lemmy's Rust-based one, with the goal of building in a handful of different features. The dev is looking at using this compatibility to migrate their instance over to the new platform, while allowing the community to use their apps of choice.

Nah, Java is alright. All the old complicated "enterprise" community and frameworks gave it a bad reputation. It was designed to be an easier, less bloated C++ (in terms of features/programming paradigms). It's also executed fairly efficiently. Last time I checked, the same program written in C would typically take 2x the time to complete in Java; whereas it would take 200x the time to complete in Python. Here's some recent benchmarks: https://benchmarksgame-team.pages.debian.net/benchmarksgame/fastest/python3-java.html

I haven't had a chance to try Rust yet, but want to. Interestingly, Rust scores poorly on source-code complexity: https://benchmarksgame-team.pages.debian.net/benchmarksgame/how-programs-are-measured.html#source-code
