Hi Sergey,
>> If exception mapper returns null instead exception, business method should
>> be invoked with "bad response".
> Can you clarify this point please ? I think if the mapper does not map then
> Response needs to be returned as is
I mean the following case:
Client receives "bad response", mapper is registered and invoked, but it
doesn't map Response to exception (method fromResponse(Response response)
returns null).
I propose that runtime will call business method with received response (as it
is) and user still has the possibility to react on error in business code.
WDYT?
Regards,
Andrei.

> Reporter: Andrei Shakirin
> Assignee: Andrei Shakirin

> TestCase:
> JAX-RS annotated business method returns Response.
> ExceptionMapper is registered on the client side.
> Current behavior: If method throws RuntimeException, exception mapper is
> invoked for all methods except returning Response ones.
> Desired behavior: Invoke exception mapper for methods returning Response as
> well, however only for "bad responses" status is >= 300. If exception mapper
> returns null instead exception, business method should be invoked with "bad
> response".
> The reason: as far as user registers exception mapper on the client side (it
> is not mandatory), it makes sense to handle all errors in consistent way via
> exception mapper. In some special cases, when user would like to process
> "bad" HTTP Response in the business method, he can return null instead
> exception in exception mapper.
