io.netty.handler.codec.CorruptedFrameException: Empty Packet!

[L4BORG]

SpigotMC/BungeeCord#1739

is this by any chance PaperSpigot issue? Cause I'm running latest PaperSpigot and latest BungeeCord...

I highly doubt this is a PaperSpigot issue.
I don't see why md_5 thinks it is.

also this would occur...

You are using a broken proxy.
Please try giving a less hostile proxy, like Waterfall, a try.

In all seriousness, I do not see how this is related to Paper in any way. If we get some evidence to the contrary we will of course look into it, however, I see no cause to blame Paper in this matter.
