Java Tool to check whether an Object instance is Serializable

Ever got the Exception while developing your Web Application:

java.io.NotSerializableException:java.util.RandomAccessSubList

...

I recently ran into a similar exception while developing my application

using Spring, Wicket and Hibernate.

The message in the exception though is insufficient to easily track

which Object is actually not Serializable, because usually the culprit

lies deep in the object graph.



Fed up with this error and the pain of debugging code to find the defaulter

I decided to write up a tool to help me.



First we need to understand when an object ceases to be Serializable.

1) When the object does not directly or indirectly implement

the Serializable interface.

2) When a member of the object is not Serializable.

3) In case of Collections when one of the elements inside the

collection is not Serializable.



So I decided to use the Reflection api in java to write up a class that

will notify whether an object is Serializable or not.





The Java Code:

import java.io.Serializable;

import java.lang.reflect.Field;

import java.lang.reflect.InvocationTargetException;

import java.lang.reflect.Method;

import java.lang.reflect.Modifier;

import java.util.ArrayList;

import java.util.Collection;

import java.util.List;
