Hi! There is "How to use PATCH method in CXF" thread http://stackoverflow.com/questions/32067687/how-to-use-patch-method-in-cxf
Where author is using use.async.http.conduit to allow proxy client generated to work. To do this he recommends to write interceptor: if ( message.get(Message.HTTP_REQUEST_METHOD).equals("PATCH") { message.put("use.async.http.conduit", true);} Does this is preferred workaround to make PATCH method work in client?
