The answer is hopefully. There is optimistic binary compatibility, which
says that we can create a new API method and hopefully you haven't already
created the same method in your subclasses. This is probably what we will
shoot for. For example, if Eclipse adds a new method to
MultiPageEditorPart, and I already that method in my subclass, I'm broken.
I don't think "real" binary compatibility exists. That would mean that no
API could be added to "framework" classes such as Figure.
Eclipse has had blatant breaks in the past, such as adding dispose() to
IEditorActionBarContributor in 2.0. Clearly all implementors of the
interface were broken. I keep reading things that say "Eclipse X.x will be
binary compatible unless otherwise noted", but I can never find where the
exceptions are noted.
