What steps will reproduce the problem?
1. When Json object has to parse large amount of json response, due to 
salesforce governance limits it will throw "Too many scripts error".

What is the expected output? What do you see instead?

I am expecting Json object to parse my json response but due to too many 
loopings to parse the data I am getting error.


What version of the product are you using? On what operating system?

SalesSforce, Apex

Please provide any additional information below.

What steps will reproduce the problem?

This should fail, but does not:

1. System.assertEquals('}', new JSONObject().ValueToString());


What is the expected output? What do you see instead?

new JSONObject().ValueToString() should return "{}", not "}"

Please provide any additional information below.

Because ValueToString appends trailing commas to all values, it removes the
last comma in its return statement:

ret.substring(0,ret.length()-1) + '}'

This, of course, is buggy if no values were appended.

Fixes are: 

a. add a trailing space to the "ret" initializer:

string ret = '{ '; // note trailing space

or

b. abandon the substring call (which is performant in java but not
necessarily other languages - unsure of how Apex handles it) and instead
append leading commas for all values except the first..

public String valueToString() {
  string ret = '{';
  for ( string key: this.keys() ) {
    if (ret.size() > 1) ret += ',';
    ret += '"' + key + '": ' + this.getvalue(key).valueToString();
  }
  return ret + '}';  
}

The leading JSON Parser from Douglas Crockford 
(http://www.json.org/json2.js) and www.JSONLint.com apparently don't like 
the LValue keys to be without quotes.

Example: {foo: "bar"} should be {"foo": "bar"}

JSONObject.valueToString() doesn't emit quotes around keys. I've updated 
this method as follows to appease various JSON parsers...

public String valueToString() {
    string ret = '{';
    for ( string key: this.keys() ) { 
        ret += '"' + key + '": ' + 
this.getvalue(key).valueToString() + ',';
    }
    return ret.substring(0,ret.length()-1) + '}';
}

Attempting to parse an escaped double quote in a double quoted string gave an 
error:

08:56:58.427|FATAL_ERROR|superpat.JSONObject.JSONException: Expected a , or }

Class.superpat.JSONObject.<init>: line 201, column 23
Class.superpat.JSONObject.JSONTokener.nextValue: line 1303, column 35
Class.superpat.JSONObject.<init>: line 186, column 25
Class.superpat.JSONObject.<init>: line 219, column 6
Class.superpat.SimpleGeo.getContextFromAddress: line 32, column 16
AnonymousBlock.superpat: line 3, column 22

The problem was in parsing

{"latitude":37.793755,"longitude":-122.395584,"address":"\"1 Market St, San 
Francisco, CA\""}

Looking at the code, it looks like this was on the 'to do list' :-) I fixed 
enough to get my code working, but I couldn't figure out the Apex for

sb.append((char)Integer.parseInt(next(4), 16));

to handle \u and \x :-/

Patch attached.

Hi

This parser works fine with Google APIs. I am trying to use elance API to 
search for the jobs and it throws me an exception "Expected a , or }". The JSON 
response of elance and Google looks different.

Would I have to modify this class so that it work with elance API?


Thanks
