[SOLVED] Playing sounds causes ConcurrentModificationException

So I am making a Forge 1.12 mod that can play note block song (.nbs) files. But when I tried to play note block sounds to the client:

 

String name = Instrument.getInstrument(note.getInstrument()); // One of "block.note.harp", "block.note.bass", "block.note.basedrum",...
float pitch = (float)Math.pow(2.0D, (double)(note.getKey - 45) / 12.0D);  // Ranges from 1 to 2.
Minecraft.getMinecraft().player.playSound(new SoundEvent(new ResourceLocation("minecraft", name)), 1F, pitch);

 

it throws ConcurrentModificationException:

[8 | 22/4/2018 14h07:55] [main/FATAL]: Unreported exception thrown!

Another thing to note is the mod plays multiple sounds at once.

Is this the right way to play multiple sounds in Forge? Or is there another way to handle this?

So when I called EntityPlayerSP#playSound, it was run on both logical sides?

pretty much, you should be able to just surround your code with an world.isRemote check

I tried surrounding my code with World#isRemote on both Minecraft.player.world and Minecraft.world but it still crashes... Super confused.

Both of those are client side only. As soon as the server tries to load the Minecraft class, it fails to find it.

You're already being passed a world object, somewhere. Post more of your code.

You're creating your own threads?

Yeah, that won't create problems, ever.
