[1.8][SOLVED]Memory leaking

[NovaViper]

Oh wait... I noticed that the JakanJump isn't working. And by not working I mean the entity isn't jumping, but the Zertums are

 

here is the code

package common.zeroquest.network.imessage;

import common.zeroquest.ZeroQuest;
import common.zeroquest.entity.EntityJakan;
import io.netty.buffer.ByteBuf;
import net.minecraft.entity.Entity;
import net.minecraft.potion.Potion;
import net.minecraftforge.fml.common.network.ByteBufUtils;
import net.minecraftforge.fml.common.network.simpleimpl.IMessage;
import net.minecraftforge.fml.common.network.simpleimpl.IMessageHandler;
import net.minecraftforge.fml.common.network.simpleimpl.MessageContext;

public class JakanJump implements IMessage{

public int entityId;

 public JakanJump(){}
 public JakanJump(int entityId)
 {
	 this.entityId = entityId;
 } 

    @Override
    public void fromBytes(ByteBuf buf) {
    	entityId = buf.readInt();
    }

    @Override
    public void toBytes(ByteBuf buf) {
        buf.writeInt(this.entityId);
    }


    public static class Handler implements IMessageHandler<JakanJump, IMessage> {

   	 public Handler(){}
	@Override
	public IMessage onMessage(JakanJump message, MessageContext ctx) {

		Entity target = ctx.getServerHandler().playerEntity;
        if(!(target instanceof EntityJakan))
        	return null;
        
        EntityJakan dog = (EntityJakan)target;
		if(dog.onGround) {

			dog.motionY = 2F * 2 * 0.1F;
			if(dog.isPotionActive(Potion.jump))
				dog.motionY += (double)((float)(dog.getActivePotionEffect(Potion.jump).getAmplifier() + 3) * 0.1F);
			dog.isAirBorne = true;
		}
		return message;
	}
    }
}
