[1.7.10] SimpleNetworkWrapper crash

[gegy1000]

I've recently started using the SimpleNetworkWrapper for sending packets, but when I start the server I get this crash: http://pastebin.com/KndVFmUp

 

I have no idea what is causing this, if anyone could help I would be very grateful.

First of all, please do not implement IMessage and IMessageHandler on the same class.

Then: Even if the packet is only received on the client you cannot use client-only classes in it, since of course the server needs to load the class as well, to send the packet.

 

Tried this, still crashes with the same log, what are we doing wrong? D:
