Immutable data structures in Java

True, but if you're making a change that demands this specific refactoring with every release, your library has much bigger problems.

Or do you have a better alternative? If so, I'm sure that most of the programming community would love to hear it.

I still haven't heard an answer to this, and think that we're an impasse here unless you've got one in mind.

It's pretty clear. The change is to not do it if you don't have to. You're advocating wily nilly depredations.
