Spec Leads,



Christian Kaltepoth from the MVC API Expert Group informed us
) that the JAX-RS 2.0 API is ambiguous regarding the order of multiple
exception mappers and parameter converter providers. He filed two JIRA
tickets ( and about that.


I agree with Christian that it is highly problematic to not have a defined
order here, and that the most obvious solution simply would be to allow
@Priority for both use cases.


Hence I would kindly ask the spec leads to allow the EG to discuss this
proposal and hopefully adopt it to JSR 370.
