Hello experts,
please see my last comment on the issue:
http://java.net/jira/browse/JAX_RS_SPEC-170
It seems that we need some more hands-on experience with the problem but we're running out of time. So I have decided to take a minimalistic approach for now that could be later extended as we become more experienced with the use cases.
Let me know if you have any objections,
Marek
