Wasn’t aware of that library - it looks a bit similar but the one in Pellet doesn’t require a logging implementation (comes with one built in), and doesn’t support SLF4J configuration - just does structured logging as the one option for now. It does bridge SLF4J calls though, they’ll just get funneled in to the built-in logger. That could be a positive or a negative depending how you feel about it 🙂
