Or, if your other fix is complicated and it only deals with alternative line
endings (which is not common in the real world), it can be a different
changeset, but make sure it's after the fix you want to backport into JDK 11.
Even though, if one day we find another bug that should be backported into JDK
11 but it depends on your new change, we will need to decide how to backport it
cleanly.
