By the same mechanism. Thread local proxies are injected. So when you
make a call to access the HttpHeaders in a writeTo method the proxy
will defer to an instance stored on the current thread.

Ah, i think that explains things then. If you move to 1.0.1 you should
get an error.
Note that for 1.0.1 there is no need to annotated spring-based beans
with Jersey-based life-cycle annotations as the life-cycle is
determined by Spring. Thus such Jersey-based annotations will be
ignored.
