Problem Description

All players from my server get kicked.

@Rayzr522 @I-Al-Istannen does this have to do with the reflective methods in the no-collisions module?

Sorry, I was a bit busy the last few days.

It is an error in a packet listener.
But that error says that the player field was null in a packet, which I don't think a normal server sends (at least no server I tried did that and it makes no sense at all to do it).

But the exception is caught and should not kick the players:
In fact, I just tried it and threw the NPE myself --- nobody was kicked. I suspect that another plugin might not handle the corrupted packet that is being sent correctly.

I could say a bit more if the server had debug mode enabled in the server.properties @ZoneTriplu.

i'll enable

Could reproduce it once randomly and then never again, but I have an idea of the cause.

Can you see if the attached version works? Also, do you have any way to consistently reproduce it?

OCM.zip

It's possible from ProtocolSupport?

https://hastebin.com/exirurumak.rb that's with debug mode

The debug mode from the server properties? If so, is that the full output you get?
Also, can you link the protocol support plugin you use?

I have also a error with packet_handler

@Tigerpanzer02 Regular spigot? Does it happen when a player instantly leaves again after joining?

Yes regular spigot

Don´t know if it only on fast leaves. I will have a look on console when it will throw again

@Tigerpanzer02 @ZoneTriplu Is this issue still present in the latest test version of OCM?
