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.
(Confirmation bias, ENGAGE!)
We have a few of those projects coming up as well. Thankfully, I just get to poke at the apps to make sure the issues are resolved.
But yeah, one of my examples of rogue threads is a coding issue, not inherently a language issue. Even log4j issues can’t be completely blamed on Java “The Language”.
