>From what I remember the difficulty was to setup preemptive authentication (by default XWiki does not send any challenged especially when guess has the right to access) since it's quite a pain in HTTPClient 4.3.
You can find a REST access example (with authentication) using HTTPClient 4.3 on https://github.com/xwiki/xwiki-commons/blob/master/xwiki-commons-core/xwiki-commons-extension/xwiki-commons-extension-repositories/xwiki-commons-extension-repository-xwiki/src/main/java/org/xwiki/extension/repository/xwiki/internal/XWikiExtensionRepository.java#L122. The client is created in https://github.com/xwiki/xwiki-commons/blob/master/xwiki-commons-core/xwiki-commons-extension/xwiki-commons-extension-repositories/xwiki-commons-extension-repository-http/src/main/java/org/xwiki/extension/repository/http/internal/DefaultHttpClientFactory.java#L53.
