It depends on a dozen details, but one of the strengths of a language like Java for me atleast is that it's pretty easy it is to do those things fairly bug-free

It depends on a dozen details, but one of the strengths of a language like Java for me atleast is that it's pretty easy it is to do those things fairly bug-free. One of the biggest dimensions that completely change this conversation is: module boundaries. If you're in a position to touch all of your user's code, it's night and day vs if you're pushing migrations on other teams or God forbid customers. But if you have all of your code? In Java atleast, it's cake.
