Error in mixins Shadow that works

[X-com]

I have this issue where this line of code gives an error, however it works when running the code.

@Shadow(aliases="val$networkmanager")

full code

import io.netty.channel.*;
import io.netty.handler.timeout.ReadTimeoutHandler;
import net.minecraft.network.*;
import org.spongepowered.asm.mixin.Final;
import org.spongepowered.asm.mixin.Mixin;
import org.spongepowered.asm.mixin.Overwrite;
import org.spongepowered.asm.mixin.Shadow;

@Mixin(targets="net.minecraft.network.NetworkManager$5")
public class MixinNetworkManager$5 {

    @Shadow(aliases="val$networkmanager") private @Final NetworkManager field_179248_a;

    @Overwrite
    protected void initChannel(Channel p_initChannel_1_) throws Exception {
        try
        {
            p_initChannel_1_.config().setOption(ChannelOption.TCP_NODELAY, Boolean.valueOf(true));
        }
        catch (ChannelException var3)
        {
            ;
        }

        p_initChannel_1_.pipeline().addLast("timeout", new ReadTimeoutHandler(0))
                .addLast("splitter", new NettyVarint21FrameDecoder())
                .addLast("decoder", new NettyPacketDecoder(EnumPacketDirection.CLIENTBOUND))
                .addLast("prepender", new NettyVarint21FrameEncoder())
                .addLast("encoder", new NettyPacketEncoder(EnumPacketDirection.SERVERBOUND))
                .addLast("packet_handler", field_179248_a);
    }
}

My specs:
Target platform: mixin (in liteloader)
IDE: Intellij 2017.2.6
OS: Windows 7

Can you share which error you get? I cannot reproduce it.

Sorry for being a bit noob. Pokechu22 helped with the code and I might not be much help other then show the errors and such.

Oh, interesting. Generally it ignores shadows with aliases, but it seems like it doesn't detect them correctly if you have just a single alias and don't use the array syntax.

Simply put, can you try if changing

@Shadow(aliases="val$networkmanager")

to

@Shadow(aliases={"val$networkmanager"})

avoids the error?

Thanks that fixed it!

No more error and it works too.
