HTTP Proxy authentication fails

When using http proxy, which requires authentication, in order to connect with s3, it fails with

Caused by: org.jclouds.http.HttpResponseException: request: HEAD https://xxx.xxx.xxx.xxx.s3.ap-northeast-1.amazonaws.com/ HTTP/1.1 failed with response: HTTP/1.1 407 Proxy Authentication Required

It works with SOCKS proxy with authentication, but fails with HTTP proxy with authentication
