"Incredibly minor": not even close. This is the very worst sort of change to have to make, because you can't do it automatically, and doing it manually is fraught with opportunities for bugs.

Not to mention that the natural pedagogical order will change in several cases that a simple "translation" wouldn't reflect. A lot of CS2 books in Java---especially two or three years ago---spent a lot of time and trouble showing how to build a generic linked list using Object, casts and all, and then as a little addendum, introduced "generics" that let you use a specific type. By translating the book from old Java to Java 1.5 without rewriting it, they were losing pedagogical opportunities and introducing confusion. Or the CS2 book in Java that used .clone() all over the place: wtf, until you realise that it's been translated from an equivalent C++ book that used copy constructors a lot. Laaaaame.

So yeah, the publisher that treats this as an "incredibly minor change" is one whose books you should avoid.
