Resuming AsyncResponse with GenericEntity respects the given MediaType but not generic type. This can be worked around by supplying a response object but the problem may be rather tricky to spot.
As a fix I propose that when GenericEntity is given then methods generic return type isn't used. This approach is taken already in resolveContentTypeByAccept of ResourceMethodInvoker.
