Keep getting this error in console: I don't THINK I have the wrong version but I may be wrong?

I think ProtocolLib 4.8.0 does not support Java 19. Please try if it works with Java 17

GENIUS! fixed it, thank you! do you know why it's inccompatible with 19? or is it just one of those things

ProtocolLib uses tons of reflections and newer Java versions are not guaranteed to be backwards compatible with respect to reflections. I think the latest Snapshot of ProtocolLib supports Java 20 but I am not sure if it is already compatible with Minecraft 1.19.2.
