JacksonFeature ExceptionMappers leaks implementation details

[feinstein]

The JacksonFeature ExceptionMapper<JsonParseException> and ExceptionMapper<JsonMappingException> Exception Mappers return the full error message as the Response body and there's no way to catch it and remove it.

I have an AutoValue class that Jackson tries to convert from JSON, if there's an error in the conversion (my AutoValue class doesn't accepts empty strings for its name field), I get a 400 Response with the text:

Cannot construct instance of `com.example.vo.AutoValue_User$Builder`, problem: Last name is null or empty.
at [Source: (org.glassfish.jersey.message.internal.ReaderInterceptorExecutor$UnCloseableInputStream); line: 14, column: 1]

I tried to use an ExceptionMapper<Throwable> to catch all exceptions, log them, and return an empty Response, but it didn't work. I also tried to make my own version of the ExceptionMapper<JsonParseException> and ExceptionMapper<JsonMappingException> as it was suggested to me, but this didn't work either (worked on Tomcat, but not on other servlet containers).

Is it there a way to remove this body message?
Could you guys remove this or make it a separate module so only those interested would include it, and the rest of us could just catch those exceptions in our own Exception Mappers?
