JSON parsing exception-Net.sf.json.JSONException:java.lang.reflect.InvocationTargetException

Note: In the project, I use the original AJAX request data, Jsonobject did not help me to parse, when I did not give me an error, I was in the JUnit unit test when testing, found. Found many times, especially through the AJAX request, do not give us an error, very depressed, especially IE, There are some problems that need to be analyzed using Firefox's return results.

Of course, Firefox does not complain at times.

Exception stack:

This problem describes the use of JSON to encapsulate an object, for a date format, to report the error.

Some people say that the object's Getter designation package (Java.uti.Date) is possible, but I found that the test can not.

My solution is reference: http://segmentfault.com/q/1010000000095526
