This behavior is actually referenced in the Servlet specification, see
Section 3.12 of the Servlet 3.1 specification.
While it mentions request objects, I think it can be implied that
other request-related object such as the async context may be recycled
as well and as such the developers should be aware that using them
outside their lifetime may produce undefined results.

Yes.

I recommend, however, that you upgrade to Jetty 9, and use the
standard Servlet API rather than Continutions.
