Ever torn your hair out at the vague 'java.io.IOException: The received string length is longer than maximum allowed (36 > 16)' while debugging a modpack?
Well, good news! I made this mod SPECIFICALLY to replace that with something much more debuggable.
While installed, those exception messages will include the actual offending string, amongst other info (e.g. 'java.io.IOException: [WTFWTP] String too long: length=36, max=16, encodedBytes=36, badString="d889a435-e371-480a-af3a-e77a0e89db54"'), to (hopefully) allow for much easier pinpointing of any troublesome mod(s) in your packs.
Enjoy!
