Hey i got an issue based on deserialization with jackson, here what i've tried and the error i got.

ERROR : com.fasterxml.jackson.core.JsonParseException: Unexpected character ('}' (code 125)): was expecting double-quote to start field name

Java Code

List<Contact> ds = mapper.readValue(data, mapper.getTypeFactory().constructCollectionType(List.class, Contact.class));
 //OR this one
List<Contact> ds = mapper.readValue(data, new TypeReference<List<Contact>>() {});
My JSON
        "id": "200",
        "name": "Alexia Milano",
        "email": "[email protected]",
        "prenom": "xx-xx-xxxx,x - street, x - country",
        "id": "201",
        "name": "Johnny Depp",
        "email": "[email protected]",
        "prenom": "xx-xx-xxxx,x - street, x - country",
If you use json validator, you can see more detailed error message:
Parse error on line 6:
...ntry",            },    {        "id
---------------------^
Expecting 'STRING'
you have extra comma there after "xx-xx-xxxx,x - street, x - country". If you remove it from both two places, you have valid JSON and Jackson parsing works.
You can enable ALLOW_TRAILING_COMMA (allowing a comma after the last value in an object or array), and then it parses it correctly, not having to modify the json and remove the comma:
jsonFactory.configure(JsonReadFeature.ALLOW_TRAILING_COMMA.mappedFeature(), true)
