Yeah, app_requested looks part of normal server.shutdown() flow. But it probably isn't the true cause of the error. What is probably happening is the RPC isn't completing in time and then you call server.shutdownNow(), which closes the connection. That connection closure is what actually causes the error.
When the connection closes there's not too much error information available. The client ends up saving the earlier GOAWAY (from shutdown()) in hopes it is related to the connection closure and sheds light on debugging.
