[1.14.4] Entity that implements IRendersAsItem crashes server during loading


Recommended Posts

I have an entity that implements IRendersAsItem so that it can be used with SpriteRenderer. However, when this entity is registered, it causes the server (but not the client) to crash with a NoClassDefFoundError saying that it cannot find this interface (which makes sense since it is annotated to indicate that it can only be loaded on the client).


I could remove the entity's implementation of IRendersAsItem and replace how it is currently rendered with an emulation of SpriteRenderer but I'm not sure if this would the correct way to solve this issue.


Current implementation of entity class:

public class EntityExplosivePotion extends ThrowableEntity implements IRendersAsItem {
    public EntityExplosivePotion(EntityType<? extends ThrowableEntity> type, World worldIn) {
        super(type, worldIn);

    public ItemStack getItem() {
        return new ItemStack(this.isSpicy() ? ModItems.SPICY_THROWABLE_EXPLOSIVE_POTION : ModItems.THROWABLE_EXPLOSIVE_POTION);

    public IPacket<?> createSpawnPacket() {
        return NetworkHooks.getEntitySpawningPacket(this);

Registration of entity:

@EventBusSubscriber(modid = Main.MOD_ID, bus = EventBusSubscriber.Bus.MOD)
class ModSetup {
    static void registerEntities(RegistryEvent.Register<EntityType<?>> event) {
        event.getRegistry().register(EntityType.Builder.<EntityExplosivePotion>create(EntityExplosivePotion::new, EntityClassification.MISC)
                .size(0.25f, 0.25f).setTrackingRange(2).setUpdateInterval(5).setShouldReceiveVelocityUpdates(true)

Registration of entity renderer:

@EventBusSubscriber(modid = Main.MOD_ID, value = {Dist.CLIENT}, bus = EventBusSubscriber.Bus.MOD)
public class ClientProxy {
    public static void init(FMLClientSetupEvent event) {
        RenderingRegistry.registerEntityRenderingHandler(EntityExplosivePotion.class, m -> new SpriteRenderer<>(m, Minecraft.getInstance().getItemRenderer()));
