No Exceptions Occur with Invalid JSON String

[jredfox]

Original issue found here and still persists in current library:
fangyidong/json-simple#16

Test code no exceptions occur when it should occur:

Test 2 this is an invalid json string due to a dupe key when parsing. It''s fine if you want to replace a key using JSONObject.pu() in memory but, when parsing it from a file/invalid sting if they key already exists in that file/string then it is no longer acceptable

JSONParser parser = new JSONParser();
System.out.println("Done:" + parser.parse("{\"key\":1 \"key\":2}"));

I actually think it is better to be liberal with input and conservative with the output. Is there any case in which it is necessary to actually check for this? I can't think of any practical cases.

[jredfox]

no read the code there are no commas and it was still parsing

[RalleYTN]

I will try to add a new method in the JSONParser which will validate JSON according to format definition.

Fixed with newest commit.
By adding true as a second parameter to parse you will enable strict mode which will validate the existence of colons and commas. Adiitionally JSONObject and JSONArray now have new constructors that allow parsing with strict mode.

This code will now throw a JSONParseException:

JSONParser parser = new JSONParser();
System.out.println("Done:" + parser.parse("{\"key\":1 \"key\":2}", true));
