Subject Re: [crypto] package access on ivars?
Date Tue, 08 Nov 2016 07:34:43 GMT
I don't think binary compatibility should include package level access, as
long as that package is only used within a single Commons JAR, then we are
free to change those, at least in a new minor release. (I would say even
patch level unless serialisation is used).

In particular, package level access means "don't touch" - it is of course
possible to break into it by compiling into "our" package, but I don't see
that as much different than introspection that changes access modifiers and
is not something we should support.

So I would say we can fix it and release it as a new minor version.
