How to resolve MalformedJsonException: Unterminated object that exist even after setting JsonReader to lenient

I am trying to parse two json files and convert them to Map<String, Object> using gson but while doing the above convertion using gson i am getting com.google.gson.stream.MalformedJsonException: Unterminated object exception.

I have my json file like below:

{"obj":
    {
        "thumbnail":"data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAMAAAACQCAYAAABeUmTwAAAW==",
        "file":"2",
        "CreatedOn":"Mon May 13 16:24:52 IST 2019"
    },
    "Status":"Created",
    "Modified":"false",
    "Tags":{"Business":"No","Entertainment":"Yes"}
}

The problem is if there is some space in json object or ":" then it is throwing that error, I have tried setting JsonReader to Lenient as well but that also didnot help

And i have tried with the below code:

    JSONParser parser1 = new JSONParser(new FileReader("D:/New Folder/2.json"));
    Object obj1 = parser1.parse();

    JsonReader reader1 = new JsonReader(new StringReader(obj1.toString()));
    reader1.setLenient(true);

    Type mapType = new TypeToken<Map<String, Object>>(){}.getType();

    Map<String, Object> firstMap = gson.fromJson(reader1, mapType);

It is throwing me the below Exception

Is there any thing else i should do to overcome the exception?

Solution

im not sure why you need the JsonParser and reader in this use case.

i think you can accomplish what you wanted in the following:

byte[] encoded = Files.readAllBytes(Paths.get("<your path>"));
Type mapType = new TypeToken<Map<String, Object>>(){}.getType();
Map<String, Object> firstMap = new Gson().fromJson(new String(encoded, Charset.defaultCharset()), mapType);

and make sure that the json is valid
