Unhandled exception in router

[IBPrivate]

I do get more errors in the last time about "Unhandled exception in router".

I added logging:

router.route().failureHandler(routingContext -> {
    Throwable failure = routingContext.failure();
    if (failure != null) {
        failure.printStackTrace();
    } else {
        Server.log("A failue without throwable has occured:");
        Server.log("RequestURL: " + routingContext.request().absoluteURI());
        Server.log("Requested URL: " + routingContext.request().path());
        Server.log("HTTP-Method: " + routingContext.request().method());
        Server.log("Header: " + routingContext.request().headers());
        Server.log("Body: " + routingContext.body().asString());
        if (routingContext.request().authority() != null) {
            WebSK.log("Host: " +  routingContext.request().authority().host());
        }
    }
    routingContext.response().setStatusCode(404).end();
});

A failue without throwable has occured:
RequestURL: http://example.com:443example.com:443
Requested URL: example.com:443
HTTP-Method: CONNECT
Header: Host=example.com:443
User-Agent=Go-http-client/1.1
Body: null
Host: http://example.com

Any ideas how to supress them (or correct this issue, its kind of annoying)...

And why is routingContext.request().absoluteURI() doubled: "http://example.com:443example.com:443/"?
Shouldn't that be "http://example.com:443"?

Perhaps it is the client that is not working well? Can you enable traffic logging or capture it with Wireshark?

I cant reproduce that - I dont make the requests.
