The report points to examples/client_chat.js and the /gserver ms-survival-1 command; first reproduce the switch against the reported BungeeCord server and inspect the play.toClient packet parsing path shown in the stack trace. Done means the server switch no longer produces the protodef PartialReadError and the client continues handling packets.
