How to handle errors on 2 differents REST controller with 2 differents MediaType?

[Rapx3]

We have a quarkus app with 2 different API: V1 and V2.
V1 is consuming and producing application/xml. We have a global exception handler to handle all the exceptions on it (using @ServerExceptionMapper).

V2 is consuming and producing application/json.

We'd like to handle the exception raised in case of wrong MediaType differently if it's happening on V1 or V2. We have define a local @ServerExceptionMapper directly inside the V2 controller, but the jakarta.ws.rs.NotSupportedException is caught by the global exception handler and not the local one.

I suppose, that's because (https://quarkus.io/guides/rest):

Εxception mappers defined in REST endpoint classes will only be called if the exception is thrown in the same class.

Is it an expected behaviour that the local ExceptionMapper is not used in an error occurs in the V2 controller? Is there a way to segregate our ExceptionMappers per controller?

Thanks for you help!
