Additional context

[ishland]

It seems that sonar is the one trying to close the connection at the very first of the pipeline, bypassing all raknetify handling.
Plus it swallows the real error when doing that.

[Git-North]

the developer from sonar states that,

"[raknetify] forgot to check if the channel is still open before performing a certain action somewhere."

I do not know if this is helpful information but it is a information

[Git-North]

They also said that when

that error

happens they do not do anything with it

[ishland]

I have checked their message, the log and their code, their plugin is definitely involved.

[jonesdevelopment]

I'll look into it when I'm back home.

If necessary, I can open a PR here or at least provide as much information as I can.

I've moved the handling of packet forwarding into Unsafe so it can handle requests even if the event is triggered at the head of the pipeline.

There's two main differences between a raknetify connection and a vanilla connection:

• The pipeline tied to the channel will convert ByteBuf into a FrameData and send it to upstream raknet handling.
• Vanilla packet framing is removed in raknetify connections, as packet length is already encoded in FrameData.
