[1.8.8] Packets are now a raw type?

[61352151511]

So I understand most of this whole raw type/generic thing, I've changed my code in a few places to reflect on this (Entity/Entity Rendering) however when it comes to the Packets I don't know how I should make them paramaterized for example

@Override public Packet getDescriptionPacket() {

In a TileEntity what should that be, and with custom packets what should they be, example:

public static Packet getCustomPacket(int number) {
	CustomMessage msg = new CustomMessage();
	msg.index = 0;
	msg.num = number;

	return INSTANCE.channels.get(Side.SERVER).generatePacketFrom(msg);
}

That helps but I keep getting this in my logs

Whenever one of my custom packets is used.
