Not necessarily. It varies on a case-by-case basis and it's usually
worth doing a little repository archaeology to determine why differences
It's less about the most expedient way to do a single backport as to the
long term maintainability of the source code base. If there's an earlier
change that will make the original patch apply more easily, the
advantages of doing so, and the benefits of that to later backports,
needs to be weighed against the risks of backporting that dependency.
The refactoring we backported with the printing implementation last time
is a good example. The risk of renaming those internal classes is
minimal - especially as the new names are already in use in later JDKs -
and future backports in that area are now more likely to apply cleanly.

I agree, though it should be done under the original changes as much as
possible. See my comments on JDK-8229501.
