Should I be concerned about how well HttpServlet implements Serializable?

Question

Java

Please share your experience, if you had to develop / design applications (work in a cluster, something else) that took this fact into account: HttpServlet implements Serializable. What real cases did you have?

Should I be concerned about the correctness of the implementation of the HttpServlet successor?

There have been discussions on SO about this topic:

Why does HttpServlet implement Serializable?
Why is HttpServlet in java implements serializable?

Answer 1

IMHO, having stateful servlets is not good. And if they are stateless, then why all this?
There are sessions for this (and ideally it would be necessary without them).

Answer 2

Almost the entire modern world of Enterprise-Java lives on the use of servlets. And no one really cares that HttpServlet implements Serializable . And I have a question - how can you implement Serializable poorly if it is a marker interface that does not imply the implementation of any methods? Serialization of Serializable objects is handled by Java itself. I think that there is no need to worry about this issue, but the question "Why?" must be addressed to the JCP.
