@Matyrobbrt, do you still intend to update this PR to 1.21?

[Matyrobbrt]

Yes. ™

[embeddedt]

Is this still needed after 1.21.2?

[Technici4n]

Yes it is. @Matyrobbrt can you update this to 1.21.4 and apply pup's recommendation?

[neoforged-automation]

@Matyrobbrt, this pull request has conflicts, please resolve them for this PR to move forward.

Does Netty have a special check for CodecException, and your intention to make use of that? If not, better use a more standard Java exception IMO.

[Technici4n]

@XFactHD pointed out that vanilla already throws instances of CodecException (or rather: the derived Encoder/DecoderException) in that same class.
