title: Why my exception class needs to be serialized?
body: <p>When you extend a class with class Exception ( for creating new exception) you get a warning to have a <code>serialVersionUID</code>. I know that <code>serialVersionUID</code> plays an important role while serialization and deserialization, but when my Exception needs to be serialized? Can anyone give me a practical case in which I want my custom-exception class to have serialization and deserialization?</p>
