I have a mod that is not executing receive packet events when I run 

@Cancelable public class ReceivePacketEvent extends Event { public Packet<?> packet; public ReceivePacketEvent(Packet<?> packet) { System.out.println("PKT"); this.packet = packet; } }

 

Nothing will happen. Other events will work like on render or tick event but packet wont work. for reference I'm using this mod in a server

I get an error seemingly randomly that looks like this and im not sure where it comes from or if it affects the packet event so id say im lost

some help would be appreciated 

thankyou!
