Internal error with new HTTP client

FULL PRODUCT VERSION :


A DESCRIPTION OF THE PROBLEM :
Calling:

        HttpRequest request = HttpRequest.newBuilder()
                .uri(new URI("https://httpbin.org"))
                .GET()
                .build();

results in an internal error.

Calling the HTTP (without s) site causes a 400 return where other clients work.
