Jersey integration does not work with Jersey's SSE #82

Hi,

When using the SSE Jersey extension, the FiberHttpServlet seems to have problem integrating with Jersey's way of working. When the stream is started, I get the following stacktrace:

I think maybe it is related to the fact that FiberServletRequest does not support async management? I've seen in it that startAsync would throw an UnsupportedOperationException.
