Jersey Exception mappers not working when jackson deserialization fails

Question

I am using Jersey 2.10 with Jackson serialization/deserialization feature in my REST API.

My idea is to make my REST API to always return a standard JSON error resp

I had the same problem and solve overriding the ExceptionMapper. Perfect! One extra thing that I needed to do and were not understanding 100% was how to override the JacksonProvider for my application (I don't know if it was related to Jersey's version that I was using - 2.19). Here's my web.xml part that overrides it:

    jersey.config.server.provider.classnames
       
          com.fasterxml.jackson.jaxrs.json.JacksonJaxbJsonProvider
