> The {{copy()}} method does the following: {{copy.setHeaders( getHeaders() );}} same for parameters. It passes the reference of the {{Properties}} object w/o creating a new instance and copying the content. All subsequent instances share those and may modify those.
> To make things worse {{HttpConfiguration.DEFAULT_PUT}} is passed for {{PUT}}. If a previous configuration modified {{http.protocol.expect-continue}} to {{false}} this singleton is modified too.
