It'll throw exception before that anyway

Is it expected to print in exception only first wrong character?

Yes, because generally, we do not know where input ends (e.g. in the case of {"a": 12312:xdwadaw213123123413.....}, incorrect part may potentially be as long as whole source itself

Should we also check exception type?

checkSerializationException makes sure that only SerializationExceptions are accepted
