CustomRoutePlanner determineRoute failed with port -1 for default scheme port requests

[Jonathan Ho]

Hi,
I have
HttpClientBuilder httpclientB = HttpClients.custom()
            .setRoutePlanner(new CustomRoutePlanner(p));

where in CustomRoutePlanner's determineRoute I test the HttpHost target to see 
if it needs to go through a proxy or not.
If the HttpHost target is say https://www.test.com and it doesn't go through 
the proxy

I return new HttpRoute(target) and this throws an exception of port value of -1

the line of code is HttpRoute.java
Args.notNegative(targetHost.getPort(), "Target port");

it seems HttpHost is default port to -1 for default schema port

Is this a bug or am I doing something wrong??

For now I added this workaround
if (target.getPort() == -1) {
                int port = target.getSchemeName().equals("http") ? 80 : 443;
                target = new HttpHost(target.getSchemeName(), 
target.getHostName(), port);
                System.out.println("====determineRoute="+target.toString());
                System.out.println("====determineRoute="+target.getPort());
 }
 return new HttpRoute(target);

Thanks
