Would it be possible to add McMMO compatibility? Currently, you can shoot an arrow at/above your pet and have the arrow bounce up and down infinitely to gain unlimited experience in archery. Since the pet is considered an entity and is invulnerable, experience can be exploited.

:( Development still halted? I'm still here to help debug and test commits.

Update your mcMMO. You are probably using a very old build considering I can't even reproduce this with recent Bukkit builds nor is this necessarily an EchoPet issue.

I don't need to update anything. I am always using a compile of the latest source commits daily, as I actively debug many plugins that require me to stay up to date.

CraftBukkit 1.8.8 version git-Spigot-d97e08b-5e85956
McMMO 1.5.04-SNAPSHOT dev 67
EchoPets 2.8.1-SNAPSHOT dev 67

Considering the exploit is caused by EchoPets classifying the spawned pet as a vanilla entity that is invulnerable, I would consider this an issue on EchoPet's end - at least to add compatibility.

Easiest way to reproduce is to spawn in a pet baby cow. Then fly above it and shoot an arrow at its head.

@drtshock This is a pretty serious issue on my server and players are beginning to exploit it left and right. :( Is it possible at all to add an option to disable the invincibility of the pets until proper compatibility has been added?
