Yes, Jackson is doing that and is signaling to the client that it is
in error, 400 status code, because it has sent a malformed request
entity.
Jersey should not be logging such things unless you explicitly say so
because they are not really server-side errors.
That is why request/response logging is so useful for debugging
purposes :-)
You can also enabling tracing:
https://jersey.dev.java.net/nonav/apidocs/latest/jersey/com/sun/jersey/api/core/ResourceConfig.html
#FEATURE_TRACE
and in conjunction with response logging will give you more info
embedded in the response to how Jersey produced the response.
