Attempting to connect to a server with OCAIP with a vanilla client fails with this error message:
Internal Exception: io.netty.handler.codec.DecoderException: java.lang.IndexOutOfBoundsException: readerIndex(6) + length(1) exceeds writerIndex(6): PooledUnsafeDirectByteBuf(ridx: 6, widx: 6, cap: 6)

Client:
Vanilla Minecraft 1.20.2, launched from Prism Launcher

Server:
Minecraft 1.20.2

OCAIP 1.3.3

OCAIP config:

; Registration sha1pow zero count (complexity, higher value is more time)
sha1pow.zero=
; Registration sha1pow count
sha1pow.count=

Note that i haven't tested (because i really don't wanna renew MS tokens) but i'm nearly certain that was the bug, thanks for the report
