Bukkit

Note to self:

If I can add a way to check if a spawn egg doesn't have any mobcatcher data BEFORE canceling the nms spawn, I should be able to stop blocking all of the randomization and whatnot done for spawn eggs in vanilla minecraft.

This would fix bugs such as zombie's never being able to pick up items and wither skeleton chances would be more accurate. It would also save me the work of having to emulate these variations for future mobs.
