The EnderDragon & Wither disapier in 4 and more Seconds.

AddEntityPacket pk = new AddEntityPacket();
pk.type = this.getNetworkId();
pk.entityUniqueId = this.getId();
pk.entityRuntimeId = this.getId();
pk.x = (float)this.x;
pk.y = (float)this.y;
pk.z = (float)this.z;
pk.speedX = (float)this.motionX;
pk.speedY = (float)this.motionY;
pk.speedZ = (float)this.motionZ;
pk.metadata = (new EntityMetadata())
.putLong(0, 0L)

        pk.yaw = 0;
        pk.pitch = 0;
        pk.attributes = new Attribute[]{Attribute.getAttribute(Attribute.MAX_HEALTH).setMaxValue(20).setValue(20)};
        if (this.linkedEntity != null) {
            pk.links = new Object[][]{{this.getId(), this.linkedEntity.getId(), (byte) 1}};
        }
        player.dataPacket(pk);

this works for me
