MicroProfile Client ProblemResponseExceptionMapper is not called

[jpraet]

As observed by the code coverage, it turns out the ProblemResponseExceptionMapper is never called. Instead, the JAX-RS ProblemClientResponseFilter takes precedence, and the thrown ResponseProcessingException is being unwrapped by:

https://github.com/resteasy/resteasy/blob/120abda3249de866a8269b9fd2128ddce318eedb/resteasy-client-microprofile-base/src/main/java/org/jboss/resteasy/microprofile/client/ProxyInvocationHandler.java#L157-L162.

Can we remove the ProblemResponseExceptionMapper?
Are all MicroProfile REST client implementations guaranteed to implement this unwrapping behavior (which differs from JAX-RS)?
Or alternatively can we prevent the ProblemClientResponseFilter from being picked up by MicroProfile REST client?
