I have no idea if this is solved in anything other then 4.8.0 as aternos.org has only the spigot versions from https://www.spigotmc.org/resources/1997

Describe the bug
message from openlogin to log in gets propably caught by themis as incorrect packet

resulting in no message recieved and pages of error messages

To Reproduce
Steps to reproduce the behavior:

1. Go to aternos.org and signup

2. install paper

3. install openlogin, themis, protocollib

4. look at your chat and server logs
   logs here

Expected behavior
themis and openlogin playing nicely along with each other

Version Info
version 4.8.0 compiled on 4. 3. 2022
/protocol dump

Additional context
would like to see devbuild number something like 4.7.614 - so it is clear if it was implemented after or before certain version

im going to post this also to openlogin issues

#2165 (comment)

the point is that aternos does not allow dev builds (for security reasons), so unless aternos allows dev builds of plugins or protocollib creates a full version from 1.19.3 devbuild this will be unresolved
