#135 Can't parse string containing function (x)

[Ken Weiner]

The following valid JSON string fails to parse:

{
  "myarray" : ["function (x)"]
}

Example code:

String json = "{\"myarray\" : [\"function (x)\"]}";
JSONObject result = JSONObject.fromObject(json);

This results in the following stacktrace:

java.lang.StringIndexOutOfBoundsException: String index out of range: -1
    at java.lang.String.substring(String.java:1958)
    at net.sf.json.JSONArray._fromJSONTokener(JSONArray.java:1167)
    at net.sf.json.JSONArray.fromObject(JSONArray.java:125)
    at net.sf.json.util.JSONTokener.nextValue(JSONTokener.java:351)
    at net.sf.json.JSONObject._fromJSONTokener(JSONObject.java:1008)
    at net.sf.json.JSONObject._fromString(JSONObject.java:1201)
    at net.sf.json.JSONObject.fromObject(JSONObject.java:165)
    at net.sf.json.JSONObject.fromObject(JSONObject.java:134)

If you simply change the word "function" to any other string or remove one of the parentheses, it parses fine.

JSONObject result = JSONObject.fromObject(json);

I got the same exception with even a simpler JSON:

{
  "key": "function (a)"
}

I use a vanilla 2.4 release of JSON-lib.
