Map is omitting one curly braces

I have a json array which i am putting in a map.

  for(int i = 0; i < jsonarr.length(); i++){

                try {
                    JSONObject jsonobj = jsonarr.getJSONObject(i);

                    Iterator<Object> keysItr = jsonobj.keys();
                    while(keysItr.hasNext()) {
                        Object key = keysItr.next();
                        Object value = jsonobj.get((String) key);

                        map.put((String) key, value);

                    }
                System.out.println(map);

But when I display the map it gives me a string in which there is one curly brace missing.

Output

{
  subtype=text, 
  maxlength=22, 
  values=[
    {
      "label":"Time",
      "value":"two",
      "selected":true
    },{
      "label":"Milk",
      "value":"hot"
    },{
      "label":"sky",
      "value":"blue"
    }
  ],
  (HERE) 
  name=text-1496816623336, 
  description=sa, 
  className=form-control, 
  label=Text Field, 
  type=text, 
  required=true
}

I have used jackson and gson also but in that case they weren't even putting the whole json into map.It might be a stupid question but thanks.

EDIT :

Here is the JSON used to create the Map

[
  {
    "type":"select",
    "label":"Select",
    "className":"form-control‌​",
    "name":"select-149‌​6823185891",
    "values"‌​:[
      {
        "label":"Option 1",
        "value":"option-1",
        "selected":true
      },{
        "label":"Option 2",
        "value":"option-2"
      },{
        "label":"Option 3",
        "value":"option-3"
      }
    ]
  },{
    "type":"text",
    "label":"Text Field",
    "className":"form-control",
    "name":"text-1496823186970‌​",
    "subtype":"text"
  }
]

Hey nope there is no curly brace missing,.... format the output and you will see:

{
    subtype=text, maxlength=22, values=[
        {"label":"Time","value":"two","selected":true},
        {"label":"Milk","value":"hot"},
        {"label":"sky","value":"blue"}
    ],(HERE) 
    name=text-1496816623336, 
    description=sa, 
    className=form-control, 
    label=Text Field, 
    type=text, 
    required=true
}

Edit (answer to your comment): This is a valid Json string:

[{"type":"select","label":"select","className":"form-control‌​","name":"select-149‌​6823185891","values":[{"label":"Option 1","value":"option-1","selected":true},{"label":"Option 2","value":"option-2"},{"label":"Option 3","value":"option-3"}]},{"type":"text","label":"Text Field","className":"form-control","name":"text-1496823186970‌​","subtype":"text"}].

Formated:

[
    {
        "type": "select",
        "label": "select",
        "className": "form-control‌​",
        "name": "select-149‌​6823185891",
        "values": [
            {
                "label": "Option 1",
                "value": "option-1",
                "selected": true
            },
            {
                "label": "Option 2",
                "value": "option-2"
            },
            {
                "label": "Option 3",
                "value": "option-3"
            }
        ]
    },
    {
        "type": "text",
        "label": "Text Field",
        "className": "form-control",
        "name": "text-1496823186970‌​",
        "subtype": "text"
    }
]

In your one there is some hidden chars between "values" and the :.

If what I thing is that you expect to still have two JsonObject in the Map. The problem is that you iterate the JsonArray to put every key/value in the same Map, that means you override the previous value with the last one.

--first item : 
map.put("type","select");
--seconds item: 
map.put("type","text");

-- result
map.get("type"); //"text"

A Map is flat, you can't have two values for two keys, you could create a collection of Map to store every value like a List<Map>, on each JsonObject to iterate, you create a new Map that you store in the list
