Hi Cristian,
do you have jersey-container-servlet.jar on your class-path (this is the
module supposed to be used for Servlet 3.x support)? The reason you're
experiencing this issue is that Jersey couldn't find appropriate
AsyncContextDelegateProvider (from jersey-container-servlet module) and
it uses implementation from jersey-container-servlet-core module
(Servlet 2.x support) which fails this way.
