Description

I have registered a custom org.apache.cxf.jaxrs.client.ResponseExceptionMapper. In case the request is retried (in my case via a org.apache.cxf.clustering.FailoverFeature leveraging a RetryStrategy), the custom response exception mapper gets null as return value for response.readEntity(Class) in its fromResponse(Response response method as it seems this one can not/no longer access the response body.

IMHO javax.ws.rs.core.Response.readEntity(...) must never return null but rather throw an exception (compare with its javadoc at https://docs.oracle.com/javaee/7/api/javax/ws/rs/core/Response.html#readEntity-java.lang.Class-).
