"Unmatched response message" log for every request

I saw "Unmatched response message" log for every request.

With deep look in code, in TracingmessageConsumer.consumeMessageReceiving:132

TracingMessageConsumer.RequestMetadata requestMetadata = (TracingMessageConsumer.RequestMetadata)this.sentRequests.remove(method);
if (requestMetadata == null) {
    LOG.log(Level.WARNING, String.format("Unmatched response message: %s", message));
    return null;
}

this.sentRequests is always empty because the put operation is only called in TracingmessageConsumer.consumeMessageSending.

In parent function has this logic:

if (messageConsumer instanceof StreamMessageConsumer) {
	logString = consumeMessageSending(message, now, date);
} else if (messageConsumer instanceof RemoteEndpoint) {
	logString = consumeMessageReceiving(message, now, date);
}

If I am using web socket connecting, I am always calling consumeMessageReceiving and never use consumeMessageSending.
So the sentRequests is always empty and show warning logs.
