Why camel https4 component with proxy authentication is not working properly ?

Issue

• If I am trying to hit HTTPS URL directly using HTTPS It's able to connect and I am getting SSL handshake error -

<to uri="?httpConnectionManager.defaultMaxConnectionsPerHost=50&amp;throwExceptionOnFailure=false"></to>

• But if I am using HTTPS4 then it's not able to connect the server -

<to uri="https4://localhost?throwExceptionOnFailure=true&amp;proxyAuthHost=abc.com&amp;proxyAuthPort=80"/>

• Can you please confirm if there is any issue with HTTPS4 with Proxy configuration?
