Ah, the age-old question of how to enable a servlet to receive requests without blocking. I say we just throw the whole thing out and start over with a microservice architecture!

I'm going with B. Implementing a ReadListener is a clean and straightforward way to handle this non-blocking requirement.

Haha, C is definitely the funniest option. Creating a Callable class and delegating to a ManagedExecutorService? That's some serious overkill!

Hmm, I think D is the way to go. Defining an AsyncListener and assigning it to the AsyncContext object sounds like the most appropriate solution.

But using a Callable class with ManagedExecutorService seems more efficient and non-blocking in this scenario.
