[JERSEY-2806] Jackson serialization exception is sent in response - Java.net JIRA

[JERSEY-2806] Jackson serialization exception is sent in response - Java.net JIRA

The JacksonFeature installs these:

            // add the default Jackson exception mappers              context.register(JsonParseExceptionMapper.class);              context.register(JsonMappingExceptionMapper.class);  

Those are the ones responsible for the rendered exception.

Based on their javadocs, I would say they are more made for handling JSON data coming on the request-side, rather than response:

Implementation of ExceptionMapper to send down a "400 Bad Request" in the event unparsable JSON is received.

It makes sense when incoming JSON cannot be mapped, but when outgoing JSON fails to render, I would say it's 500 Internal Server Error, rather than 400 Bad request.
