I have included the stacktrace for more information. It's an issue with reflection.

Indeed it is. :)

cauldron-1.7.10-1.1231.04.209

That stacktrace doesn't have anything to do with EchoPet, nor does it have anything to do with entity sounds (nor do pet sounds in any way ever interact with reflection in the plugin).

I apologize. I am not awake. Here is the correct stack trace.

Ah, that looks a bit more relevant ;D

Is that a Cauldron server?
