#71 String containing special caracters can't be serialized

[philippe Kernevez]

String that containing special caracters like "{", "(" or "[", can't be serialized or deserialized.

For example this test fails:
tJsonSource.put("weirdString", "[{}][:,;:.[][[]");
assertEquals("[{}][:,;:.[][[]", tJsonSource.get("weirdString"));

A JSONArray can't deserialized a String containing this kind of caracters, like JSONObject.
This is Ok
JSONObject jsonObject = JSONObject.fromObject( "{\"weirdString\":\"[{}][:,;:.[][[]\"}", tConfig);
This fails
jsonObject = JSONObject.fromObject( "{\"weirdStringArray\":[\"{912}\",\"[Hello]\",\"[]{}[,;.:[[]\"]}", tConfig);

Tha patch contains tests and corrections for the v 2.2.2 as I can't build the trunk (tests failures).

Thanks Philippe, we'll review the patch and make the proper adjustments to the code.

I have trouble for building with maven on windows.
You may change the inner class JsonErrorDetector static.
" public static class JsonErrorDetector implements JsonEventListener{" instead of " public class JsonErrorDetector implements JsonEventListener{"

I upload a new version of the patch.
In the first one I didn't see the jdk15 source path, so only half of the code has been corrected.
This patch has been testing with the ant build instead of the Maven build.
I always have a groovy test that fails (even without my modofication). I suppose that the Groovy test can't but run with success on windows plateform.

The failing test is : TestJsonSlurper.testParseUri()
The reason is that it can't understand the root Url staring with "d:\" that is the drive where I install the project.

The full stack is

Testcase: testParseUri took 9,235 sec

Do the Groovy test be successfull with windows ?

Philippe, seems like that testcase in particular is a bit brittle. We test on Linux so that is why we never encountered the error.
And yes, the proper way to build the package is using Ant not Maven. I know, weird but is done this way because Maven can't replace a source class with the same name easily.

I think perhaps this bug hits me too. I'm having problems with a text field that has []s. Status?

[Dan F]

Hmm, I should say I might have a different bug, not sure.

This code:

JSONObject obj = new JSONObject();
obj.put("text", text);
logger.info("obj.text: " + obj.get("text"));

Fails: String text = "[0] [a]";
Okay: String text = "[b] [a]";

The failure logs:

INFO: obj.text: [0]
