Latest bukkit version breaks the plugin
Commit CraftBukkit/Bukkit 543b253dd8 changes depend, softDepend and loadBefore to use EmptyImmutableList, SingletonImmutableList or RegularImmutableList which cannot be cast to ArrayList.
This causes python loader to break.
which version? its working for me on a 1.7.2 spigot build
i have noticed it takes a longer time to load though, not sure whats causing it
I guess you're using a stable build? Try the latest dev
Why is this being cast anyway? There doesn't look to be any code that requires an ArrayList, you should really just be using List<String> depend;
EDIT: Which, to be clear, would fix this problem. (Though you should also probably do the same "replace space with underscore" thing Bukkit is now doing)
